After the passing of the Holy Prophet (s)...
After the passing of the Holy Prophet (s), a group from the Arabs would come for ziyara of Holy Prophet (s) with clear and pure minds and recite this verse and request him to seek forgiveness on their behalf. Taqi al-Din al-Subki and al-Samhudi have reported examples regarding it in their books Shifa' al-saqam and Wafa' al-wafa' respectively.
We shall mention here some of them: Sufyan bin 'Anbar, who is one of the learned scholars of the Shafi'i school, narrates from al-'Utabi - that latter was standing near the grave of the Holy Prophet (s) when an Arab came and said: السلام عليك يا رسول الله سمعت الله يقول وَلَوْ أَنَّهُمْ إِذْ ظَلَمُوا أَنْفُسَهُمْ جَاءُوكَ فَاسْتَغْفَرُوا اللَّه
