عَنْ زَيْدِ بْنِ خَارِجَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: إِنِّي سَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِنَفْسِي كَيْفَ الصَّلَاةُ عَلَيْكَ؟ قَالَ: ((صَلُّوا وَاجْتَهِدُوا، ثُمَّ قُولُوا: اللَّهُمَّ بَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ))
Sayyiduna Zaid bin Kharijah (may Allah be pleased with him) says: I myself asked the Messenger of Allah (peace and blessings be upon him) how should blessings be sent upon you? The Messenger of Allah (peace and blessings be upon him) said: Send blessings upon me and strive (in doing so), then say: O Allah, bless Muhammad and the family of Muhammad as You blessed Ibrahim; indeed, You are Praiseworthy, Glorious.
