Hāfiz Izzuddeen bin Abdus Salaam رحمه الله says;
“Our Durood upon Sayyiduna Rasulullah صلى الله عليه وسلم is by no means to be considered as an intercession by us on his behalf, because we are not in any way fit to intercede on his behalf.
In reality, Allah Ta’ala جل جلاله has ordered us to repay our benefactor for some of his favours and generosity. No other benefactor has been more generous to us than Sayyiduna Rasulullah صلى الله عليه وسلم. Due to the fact that we have been unable to repay him for his generosity, Allah Ta’ala جل جلاله has seen our weakness and shown us the correct manner of repaying Sayyiduna Rasulullah صلى الله عليه وسلم, and that is by reciting Durood upon him.
Since we are unable to fulfil this command of Allah Ta‘ala جل جلاله in the correct manner, we beg of Allah Ta’ala جل جلاله to convey Durood upon Sayyiduna Rasulullah صلى الله عليه وسلم according to His (Allah Ta‘ala جل جلاله) Majesty and Exalted position.”
(The Gift of Durood and Salaam pg.28)
يَا رَبِّ صَلِّ وَسَلِّمْ دَائِمَاً أَبَدًا عَلَىْ حَبِيْبِكَ خَيْرِ الْخَلْقِ كُلِّهِمِ
“O Sustainer, shower Salaat and Salaam forever and ever upon Your beloved, who is the best of all creation.”
جَزَی اللہُ عَنَّا نَبِيَّنَا مُحَمَّدًا صَلَّی اللہُ عَلَیْه وسَلَّمَ بِمَا هُوَ أَھْلُهُ
May Allah Ta’ala جل جلاله reward our Nabi Muhammad صلى الله عليه وسلم on our behalf such a reward that is due to Him.
