From Ummu Salamah, she said: that the Prophet ﷺ, when he finished the Fajr (dawn) prayer and gave the salutation (at the end of the prayer), he would recite:
اللَّهُمَّ إِنِّي أَسْأَلُكَ عِلْمًا نَافِعًا ، وَرِزْقًا طَيِّبًا ، وَعَمَلاً مُتَقَبَّلاً
Meaning: “O Allah, I ask You for beneficial knowledge, good provision, and accepted deeds.”
Narrated by Ibn Majah (925)
