Hadith 7:129
‘Abdallah b. Busr reported God's messenger as saying, “Blessed is he who finds a great amount of asking for pardon in his record.” Ibn Majah transmitted it, and Nasa'i transmitted in 'Amal yaum walaila. 1 1. Mirqat , iii, 78 gives this as the title of a book by Nasa’i. The only reference to this tradition in the Concordance is Ibn Majah, Adab , 57.
وَعَن عبد الله بن يسر قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «طُوبَى لِمَنْ وَجَدَ فِي صَحِيفَتِهِ اسْتِغْفَارًا كَثِيرًا» . رَوَاهُ ابْنُ مَاجَهْ وَرَوَى النَّسَائِيُّ فِي «عملِ يَوْم وَلَيْلَة»
