450. Prophet's Dua After Insulting Someone (Masnun Dua)
Narrated by Abu Huraira (RA), He heard the Prophet (ﷺ) say:
اَللَّهُمَّ فَأَيُّمَا مُؤْمِنٍ سَبَبْتُهُ فَاجْعَلْ ذَلِكَ لَهُ قُرْبَةً إِلَيْكَ يَوْمَ الْقِيَامَةِ
اَللّٰهُمَّ فَاَيُّمَا مُؤْمِنٍ سَبَبْتُهٗ فَاجْعَلْ ذٰلِكَ لَهٗ قُرْبَةً اِلَيْكَ يَوْمَ الْقِيَامَةِ
Allaahumma fa'ayyumaa mu'minin sababtuhu faj'al dhaalika lahu qurbatan 'ilayka yawmal-qiyaamah
O Allah, whomever of the believers I have abused, make it a means of gaining nearness to you on the Day of Resurrection.
451. Dua Etiquette of praising a fellow Muslim
The Prophet (ﷺ) said: "Whoever amongst you has to praise his brother should say:
أَحْسِبُ فُلَانًا وَاللَّهُ حَسِيبُهُ وَلَا أُزَكِّي عَلَى اللَّهِ أَحَدًا أَحْسِبُهُ كَذَا وَكَذَا
اَحْسِبُ فُلَانًا وَاللّٰهُ حَسِيْبُهٗ وَلَا اُزَكِّيْ عَلَى اللّٰهِ اَحَدًا اَحْسِبُهٗ كَذَا وَكَذَا
Ahsibu fulaanan wAllaahu haseebuhu wa laa 'uzakkee 'alAllaahi 'ahadan ahsibuhu kadha wa kadha
I think that he is so and so, and Allah knows exactly the truth, and I do not confirm anybody's good conduct before Allah, but I think him so and so.
It is to be said when you must ensure you have knowledge that the certain characteristic is present in that person.
452. Dua to praise Allah
One of Companions of The Prophet (ﷺ) had a characteristic that if he was praised, he would say:
اَللَّهُمَّ لَا تُؤَاخِذْنِي بِمَا يَقُولُونَ، وَاغْفِرْ لِي مَا لَا يَعْلَمُونَ، وَاجْعَلْنِي خَيْرًا مِمَّا يَظُّنُّونَ
اَللّٰهُمَّ لَا تُؤَاخِذْنِيْ بِمَا يَقُوْلُوْنَ، وَاغْفِرْ لِيْ مَا لَا يَعْلَمُوْنَ، وَاجْعَلْنِيْ خَيْرًا مِّمَّا يَظُّنُّوْنَ
Allaahumma laa tu'aakhidhnee bimaa yaqooloon, waghfir lee maa laa ya'lamoon waj'alnee khayram-mimmaa yadhunnoon
O Allah, do not call me to account for what they say and forgive me for what they have no knowledge of and make me better than they imagine.
