Uloom-ul-Hadith- 4 Obligations of Prophet صلى الله عليه وسلام.

Every Messenger was sent, for people to OBEY .
Evidence in Surah An-Nisa Ayah 64 ,
“ We sent no Messenger, but to be obeyed by Allah’s Leave. If they (hypocrites), when they had been unjust to themselves, had come to you (Muhammad ) and begged Allah’s Forgiveness, and the Messenger had begged forgiveness for them: indeed, they would have found Allah All-Forgiving (One Who accepts repentance), Most Merciful.”
Another lesson which we get from this ayah is that, in this present world, Prophet  صلى الله عليه و سلام is not alive but His teachings and Hadith are.Therefore, those who wants forgiveness from ALLAH, must seek knowledge of Hadith and act upon it. Allah will surely forgive.

Question: What are the four obligations of Prophet  صلى الله عليه و سلام ?
Answer :  Evidence of Surah A’al-Imran Ayah 164,
“Indeed Allah conferred a great favour on the believers when He sent among them a Messenger (Muhammad ) from among themselves, reciting unto them His Verses (the Qur’an), and purifying them (from sins by their following him), and instructing them (in) the Book (the Qur’an) andAl-Hikmah [the wisdom and the Sunnah of the Prophet  (i.e. his legal ways, statements, acts of worship, etc.)], while before that they had been in manifest error."
Obligations are :
1-  ”reciting unto them His Verses (the Qur’an),”
2-”purifying them (from sins by their following him),”
3- “instructing them (in) the Book (the Qur’an”.  (means giving them knowledge of Qura’n).
4-” Al-Hikmah [the wisdom and the Sunnah of the Prophet  (i.e. his legal ways, statements, acts of worship, etc.)]”  (means giving them knowledge of Hadith)
Iman Shaf’ee in His book of Ar-Risalah, Page 78 says,” I have heard from the Ahl-e-Ilm (People of Knowledge) of Qur’an whom i like that the word” Al-Hikmah ” means Sunnah of Prophet. 
Al-Hikmah in Quran means Sunnah of Prophet, than how can we reject Hadith of Prophet? Have not those who reject Hadith read Surah An-Nisa Ayah 113, “Allah has sent down to you the Book (The Qur’an), and Al-Hikmah (Islamic laws, knowledge of legal and illegal things i.e. the Prophet’s Sunnah - legal ways), and taught you that which you knew not. And Ever Great is the Grace of Allah unto you (O Muhammad ).
