Abu Hurairah reported the Prophet ﷺ as sayings:
if anyone would like to have the fullest measure granted to him when he invokes blessings on us, the members of the prophet’s family, he should say: O Allah, bless Muhammad, the unlettered Prophet, his wives who are the mother of the faithful, his off springs, and the people of his house as Thou didst bless the family of Abraham. Thou art indeed praiseworthy and glorious.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حِبَّانُ بْنُ يَسَارٍ الْكِلاَبِيُّ، حَدَّثَنِي أَبُو مُطَرِّفٍ، عُبَيْدُ اللَّهِ بْنُ طَلْحَةَ بْنِ عُبَيْدِ اللَّهِ بْنِ كَرِيزٍ حَدَّثَنِي مُحَمَّدُ بْنُ عَلِيٍّ الْهَاشِمِيُّ، عَنِ الْمُجْمِرِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ " مَنْ سَرَّهُ أَنْ يَكْتَالَ بِالْمِكْيَالِ الأَوْفَى إِذَا صَلَّى عَلَيْنَا أَهْلَ الْبَيْتِ فَلْيَقُلِ اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ النَّبِيِّ وَأَزْوَاجِهِ أُمَّهَاتِ الْمُؤْمِنِينَ وَذُرِّيَّتِهِ وَأَهْلِ بَيْتِهِ كَمَا صَلَّيْتَ عَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ " .
