'Ikrimah reports from Ibn 'Abbas that the Messenger of Allah said to 'Abbasibn 'Abdal-Mutalib: "O 'Abbas, O Uncle, shall I not give you, shall I notpresent to you, shall I not donate to you, shall I not tell you ten thingswhich, if you do, Allah will forgive your first and last sins, past and presentsins, intentional and unintentional sins, private and public sins? The tenactions are: pray four rak'at, reciting in every rak'ah al-Fatihah and a surah.And when you finish the Qur'anic recitation of the first rak'ah, say, whilestanding, 'Subhanallah, al-hamdulillah, wa la ilaha illallah, wa Allahu Akbar'['Glory be to Allah. All praise is due to Allah. There is no God except Allah.Allah is the greatest.'] fifteen times. Then make ruku', and while you are inruku', say the same ten times; then stand, and say the same ten times. Then godown and make sajdah, and while you're in sajdah, say the same ten times. Thensit after the sajdah, and say the same ten times. Then make sajdah, and say thesame ten times. Then sit after the second sajdah, and say the same another tentimes. That is seventy-five [repetitions of the phrases] in each rak'ah. Dothat in each of the four rak'at. If you can pray it once a day, do so. If youcannot, then once every Friday. If you cannot do that, then once a year. And ifyou cannot do that then once in your life." This is related by Abu Dawud,Ibn Majah, Ibn Khuzaimah in his sahih, and at-Tabarani. About this hadithal-Munzhiri says: "This hadith has been related through many chains andfrom a number of companions. The best of them is this one from 'Ikrimah. Agroup of scholars have graded it to be sahih, including al-Hafez Abu Bakral-'Ajari, (al-Munzhiri's teachers), Abu Muhammad 'Abdurrahim al-Misri, and Abual-Hassan al-Maqdisi." Ibn alMubarak says: "The tasbih prayer is agreatly desired act and it is desirable that one should punctually observe itand never neglect it.
