"The Messenger of Allah ﷺ said to Al-'Abbas: 'On the night of Monday, come to me, you and your offspring, so that I may supplicate for them with a supplication that Allah will benefit you and your children by.' So he went, and we went with at night, so he ﷺ covered us in a Kisah (shawl), then said: 'O Allah, forgive Al-'Abbas and his offspring, for what is open and what is secret, with a forgiveness that does not leave any sins. O Allah! Take care of him concerning the affair of his offspring.'"  

قَالَ رَسُولُ اللَّهِ ﷺ لِلْعَبَّاسِ إِذَا كَانَ غَدَاةُ الاِثْنَيْنِ فَأْتِنِي أَنْتَ وَوَلَدُكَ حَتَّى أَدْعُوَ لَهُمْ بِدَعْوَةٍ يَنْفَعُكَ اللَّهُ بِهَا وَوَلَدَكَ فَغَدَا وَغَدَوْنَا مَعَهُ وَأَلْبَسَنَا كِسَاءً ثُمَّ قَالَ اللَّهُمَّ اغْفِرْ لِلْعَبَّاسِ وَوَلَدِهِ مَغْفِرَةً ظَاهِرَةً وَبَاطِنَةً لاَ تُغَادِرُ ذَنْبًا اللَّهُمَّ احْفَظْهُ فِي وَلَدِهِ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ هَذَا الْوَجْهِ
