عن سيدتنا فاطمة رضي الله عنها قالت: كان رسول الله صلى الله عليه وسلم إذا دخل المسجد صلّى على محمد وسلّم وقال: ربّ اغفر لي ذنوبي وافتح لي أبواب رحمتك وإذا خرج صلّى على محمد وسلّم وقال رب اغفر لي ذنوبي وافتح لي أبواب فضلك (سنن الترمذي، الرقم: ٣١٤، حديث فاطمة حديث حسن، وليس إسناده بمتصل)
Hazrat Faatimah (radhiyallahu ‘anha) reports that when Rasulullah (sallallahu ‘alaihi wasallam) would enter the musjid, he would first recite Durood and thereafter recite the following dua:
رَبِّ اغْفِرْ لِيْ ذُنُوْبِيْ وَافْتَحْ لِيْ أَبْوَابَ رَحْمَتِك
O my Rabb, forgive my sins and open for me the doors of Your mercy.
When Rasulullah (sallallahu ‘alaihi wasallam) would leave the musjid, he would recite Durood and thereafter recite the following dua:
رَبِّ اغْفِرْ لِيْ ذُنُوْبِيْ وَافْتَحْ لِيْ أَبْوَابَ فَضْلِك
O my Rabb, forgive my sins and open for me the doors of Your bounties.
Conveying Durood on behalf of Someone at the Grave of Hazrat Rasulullah (sallallahu ‘alaihi wasallam)
Hazrat Yazeed bin Abi Sa’eed Al-Madani (rahimahullah) mentions:
On one occasion (when intending to travel to Madinah Munawwarah), I bid farewell to Umar bin Abdil Azeez (rahimahullah). Umar (rahimahullah) said to me, “I have a wish which I need you to fulfill for me.” I replied, “O Ameerul Mu’mineen! What wish do you need me to fulfill?”
He answered, “When you reach Madinah Munawwarah and you see the blessed grave of Rasulullah (sallallahu ‘alaihi wasallam), then convey my Salaams to Rasulullah (sallallahu ‘alaihi wasallam).” (Shuabul Imaan #3870)
