Tashahhud Du`a - 2 (Hadith No. 795)


Salam,
Bismillah.

Volume 1, Book 12, Number 795:
Narrated 'Aisha (the wife of the Prophet):
Allah's Apostle used to invoke Allah in the prayer saying "Allahumma inni a'udhu bika min adhabil-qabri, wa a'udhu bika min fitnatil-masihid-dajjal, wa a'udhu bika min fitnatil-mahya wa fitnatil-mamati. Allahumma inni a'udhu bika minal-ma thami wal-maghrami. (O Allah, I seek refuge with You from the punishment of the grave and from the afflictions of Masi,h Ad-Dajjal and from the afflictions of life and death. O Allah, I seek refuge with You from the sins and from being in debt)."
Somebody said to him, "Why do you so frequently seek refuge with Allah from being in debt?" The Prophet replied, "A person in debt tells lies whenever he speaks, and breaks promises whenever he makes (them)."
'Aisha also narrated: I heard Allah's Apostle in his prayer seeking refuge with Allah from the afflictions of Ad-dajjal.

In Arabic:

 اللهم إني أعوذ بك من عذاب القبر، و أعوذ بك من فتنة المسيح الدجال، و أعوذ بك من فتنة المحيا وفتنة الممات،  اللهم إني أعوذ بك من المأثم والمغرم

Another version of the same du`a:

This is not one of the mandatory du`as of tashahhud. But since Prophet (SAW) used to recite it a lot, one must try and follow this particular Sunnah as much as possible.
Wassalam.
