Islam. I live for it: hadith no 1195

Bismillah.

Volume 2, Book 24, Number 536:

Narrated Abu Huraira (radiallaahu `anhu):

Abu Bakr (radiallaahu `anhu) said, "By Allah! If they (pay me the Zakat and) withhold even a she-kid which they used to pay during the lifetime of Allah's Apostle (sallallaahu `alayhi wasallam), I will fight with them for it." 'Umar (radiallaahu `anhu) said, "It was nothing but Allah Who opened Abu Bakr (radiallaahu `anhu)'s chest towards the decision to fight, and I came to know that his decision was right."

As the news of the Prophet's death spread, a number of tribes rebelled and refused to pay Zakat (poor-due), saying that this was due only to the Prophet . At the same time a number of impostors claimed that the prophethood had passed to them after Muhammad and they raised the standard of revolt. To add to all this, two powerful empires, the Eastern Roman and the Persian, also threatened the new-born Islamic state at Medina.
Under these circumstances, many Companions of the Prophet, including Umar, advised Abu Bakr to make concessions to the Zakat evaders, at least for a time. They told him to accept their prayer from them and leave it up to Allah to judge them for denying Zakat. The new Caliph disagreed. He insisted that the Divine Law cannot be divided, that there is no distinction between the obligations of Zakat and Salat (prayer), and that any compromise with the injunctions of God would eventually erode the foundations of Islam. Umar and others were quick to realize their error of judgment. The revolting tribes attacked Medina but the Muslims were prepared. Abu Bakr himself led the charge, forcing them to retreat. He then made a relentless war on the false claimants to prophethood, most of whom submitted and again professed Islam.
The threat from the Roman Empire had actually arisen earlier, during the Prophet's lifetime. The Prophet had organized an army under the command of Usama, the son of a freed slave. The army had not gone far when the Prophet had fallen ill so they stopped. After the death of the Prophet , the question was raised whether the army should be sent again or should remain for the defense of Medina. Again Abu Bakr showed a firm determination. He said, "I shall send Usama's army on its way as ordered by the Prophet, even if I am left alone."

Bismillah.

Volume 2, Book 24, Number 496:

Narrated Abu Masud:

When the verses of charity were revealed, we used to work as porters. A man came and distributed objects of charity in abundance. And they (the people) said, "He is showing off." And another man came and gave a sa' (a small measure of food grains); they said, "Allah is not in need of this small amount of charity." And then the Divine Inspiration came: "Those who criticize such of the believers who give in charity voluntarily and those who could not find to give in charity except what is available to them." (9.79).

From Tafsir Ibn Kathir:

Among the traits of the hypocrites is that they will not leave anyone without defaming and ridiculing him in all circumstances even those who give away charity. If, for instance, someone gives away a large amount, the hypocrites say that he is showing off. If someone gives away a small amount they say that Allah stands not in need of this man's charity. Al-Bukhari recorded that `Ubaydullah bin Sa`id said that Abu An-Nu`man Al-Basri said that Shu`bah narrated that Sulayman said that Abu Wa'il said that Abu Mas`ud said, "When the verses of charity were revealed, we used to work as porters. A man came and distributed objects of charity in abundance and they (hypocrites) said, `He is showing off.' Another man came and gave a Sa` (a small measure of food grains); they said, `Allah is not in need of this small amount of charity.' Then the Ayah was revealed;

﴿الَّذِينَ يَلْمِزُونَ الْمُطَّوِّعِينَ﴾
(Those who defame the volunteers...)'' Muslim collected this Hadith in the Sahih. Al-`Awfi narrated that Ibn `Abbas said, "One day, the Messenger of Allah went out to the people and called them to bring forth their charity, and they started bringing their charity. Among the last to come forth was a man who brought a Sa` of dates, saying, `O Allah's Messenger! This is a Sa` of dates. I spent the night bringing water and earned two Sa` of dates for my work. I kept one Sa` and brought you the other Sa`. ' The Messenger of Allah ordered him to add it to the charity. Some men mocked that man, saying, `Allah and His Messenger are not in need of this charity. What benefit would this Sa` of yours bring' `Abdur-Rahman bin `Awf asked Allah's Messenger , `Are there any more people who give charity' The Messenger of Allah said,

«لَمْ يَبْقَ أَحَدٌ غَيْرُك»
(None besides you!) `Abdur-Rahman bin `Awf said, `I will give a hundred Uqiyah of gold as a charity.' `Umar bin Al-Khattab said to him, `Are you crazy' `Abdur-Rahman said, `I am not crazy.' `Umar said, `Have you given what you said would give' `Abdur-Rahman said, `Yes. I have eight thousand (Dirhams), four thousand I give as a loan to my Lord and four thousand I keep for myself.' The Messenger of Allah said,

«بَارَكَ اللهُ لَكَ فِيمَا أَمْسَكْتَ وَفِيمَا أَعْطَيْت»
(May Allah bless you for what you kept and what you gave away). However, the hypocrites defamed him, `By Allah! `Abdur-Rahman gave what he gave just to show off.' They lied, for `Abdur-Rahman willingly gave that money, and Allah revealed about his innocence and the innocence of the fellow who was poor and brought only a Sa` of dates. Allah said in His Book,

﴿الَّذِينَ يَلْمِزُونَ الْمُطَّوِّعِينَ مِنَ الْمُؤْمِنِينَ فِي الصَّدَقَـتِ﴾
(Those who defame such of the believers who give charity voluntarily) ﴿9:79﴾.''' A similar story was narrated from Mujahid and several others. Ibn Ishaq said, "Among the believers who gave away charity were `Abdur-Rahman bin `Awf who gave four thousand Dirhams and `Asim bin `Adi from Bani `Ajlan. This occurred after the Messenger of Allah encouraged and called for paying charity. `Abdur-Rahman bin `Awf stood and gave away four thousand Dirhams. `Asim bin `Adi also stood and gave a hundred Wasaq of dates, but some people defamed them, saying, `They are showing off.' As for the person who gave the little that he could afford, he was Abu `Aqil, from Bani Anif Al-Arashi, who was an ally of Bani `Amr bin `Awf. He brought a Sa` of dates and added it to the charity. They laughed at him, saying, `Allah does not need the Sa` of Abu `Aqil.''' Allah said,

﴿فَيَسْخَرُونَ مِنْهُمْ سَخِرَ اللَّهُ مِنْهُمْ﴾
(so they mock at them (believers); Allah will throw back their mockery on them) rebuking them for their evil actions and defaming the believers. Truly, the reward, or punishment, is equitable to the action. Allah treated them the way mocked people are treated, to aid the believers in this life. Allah has prepared a painful torment in the Hereafter for the hypocrites, for the recompense is similar to the deed.

Do you see the kind of behavior hypocrites had shown? Belittling, defaming and ridiculing others as if they knew what was in their hearts. As if they knew their intentions to be insincere.
It's a HUGE thing to judge someone. It is so disliked by Allah that He revealed verses in the Qur'an for it, protecting the honor of the Sahaba who has spent in His way. He dislikes this trait of hypocrisy so much that he forbade Prophet (SAW) from asking forgiveness for the hypocrites, right in the next verse:

﴿اسْتَغْفِرْ لَهُمْ أَوْ لاَ تَسْتَغْفِرْ لَهُمْ إِن تَسْتَغْفِرْ لَهُمْ سَبْعِينَ مَرَّةً فَلَن يَغْفِرَ اللَّهُ لَهُمْ ذَلِكَ بِأَنَّهُمْ كَفَرُواْ بِاللَّهِ وَرَسُولِهِ وَاللَّهُ لاَ يَهْدِي الْقَوْمَ الْفَـسِقِينَ ﴾
(80. Whether you (O Muhammad ) ask forgiveness for them (hypocrites) or ask not forgiveness for them -- (and even) if you ask seventy times for their forgiveness -- Allah will not forgive them because they have disbelieved in Allah and His Messenger. And Allah guides not those people who are rebellious.)

Bottom line: don't judge people. Don't try to defame anyone. Especially the believers. You don't know how beloved that person is to Allah. And if you hurt them, Allah might protect them.

Note: if you think you have this trait, try to fix it. Think good about people. Make 70 excuses for them before thinking bad about them. "Maybe he didn't mean to..", "Maybe he didn't know.." etc. Reflect on your own faults and flaws before looking at others'.
And if you think someone you know has this problem. Stop right there! You're being judgmental again. :P
