9ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ مَنْ قَالَ فِي دُبُرِ الْفَرِيضَةِ يَا مَنْ يَفْعَلُ مَا يَشَاءُ وَلا يَفْعَلُ مَا يَشَاءُ أَحَدٌ غَيْرُهُ ثَلاثاً ثُمَّ سَأَلَ أُعْطِيَ مَا سَأَلَ.
9. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu’awiyah ibn ‘ Ammar who has said the following: “Whoever, after every obligatory prayer says: ‘O the One who does as He wills and does not do as others will,’ three times, and pleads (before Allah) for his wishes they will be granted.’”
