عن محمد بن يحيى بن حبان عن أبيه عن جده رضي الله عنه أن رجلا قال يا رسول الله صلى الله عليه وسلم أجعل ثلث صلاتي عليك قال نعم إن شئت قال الثلثين قال نعم إن شئت قال فصلاتي كلها قال رسول الله صلى الله عليه وسلم إذا يكفيك الله ما أهمك من أمر دنياك وآخرتك رواه الطبراني بإسناد حسن (الترغيب والترهيب رقم 2578)

Hazrat Habbaan bin Munqiz (rahimahullah) reports that a certain Sahaabi once asked Rasulullah (sallallahu ‘alaihi wasallam), “O Rasul of Allah (sallallahu ‘alaihi wasallam), should I devote one-third of the time I have allocated for du‘aa to recite durood upon you?” Rasulullah (sallallahu ‘alaihi wasallam) replied, “Yes, if you wish.” The Sahaabi then asked, “Should I devote two-thirds of that time for reciting durood upon you?” Rasulullah (sallallahu ‘alaihi wasallam) again replied, “Yes, if you wish.” The Sahaabi then asked, “Should I devote all of that time for reciting durood upon you?” Rasulullah (sallallahu ‘alaihi wasallam) responded, “If you do so, Allah Ta‘ala will suffice you of every need which you have (and you would have asked for in your du‘aa), whether it relates to your dunya or your Aakhirah.”
