It is reported from Hadhrat Umme Salamah t that after Nabi-e-Kareem صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَم turned his head
in Salaam in the Fajr Salaah, he would make this Duaa:
O Allaah I seek from You beneficial knowledge, accepted actions and pure sustenance.”
Benefit: The foundation among these three things is Halaal sustenance. If one’s sustenance is not Halaal and pure, one’s knowledge will no be beneficial nor will one’s actions be accepted. By beneficial knowledge is meant that knowledge which benefits a
person in the Aakhirat. If there is no benefit in the Aakhirat, such knowledge is the source of misfortune. This is why Nabi-e-Kareem صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَم sought protection from such knowledge which is not beneficial. If actions are not accepted, one has achieved nothing besides the difficulty of having acted upon it. If sustenance is not Halaal, both one’s worldly life and Deen are destroyed. It is a source of loosing blessings in the world and difficulties mcoming one’s way and going to Jahannum in the next world. This is why Nabi-e-Kareem صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَم made Duaa for these things. The morning is the time for the allocation of sustenance because of which He صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَم used to made Duaa for pure sustenance after the morning Salaah.
Therefore O people, make this Duaa after the Salaam of the Fajr Salaah so that you activate the means of earning pure and wholesome sustenance can be created and set in motion.
