It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Abu Jahl came to the Noble Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) was offering prayer. He (Abu Jahl) tried to prevent him (peace and blessings be upon him) from praying, so the Noble Prophet (peace and blessings be upon him) warned him. He (Abu Jahl) said: "Are you threatening me? By Allah! There is no one in this valley who has a greater assembly than mine." Then Allah Almighty revealed these verses: {أَ رَأَ یْتَ الَّذِی یَنْہٰی عَبْدًا إِذَا صَلّٰی أَ رَأَ یْتَ إِنْ کَانَ عَلَی الْہُدٰی أَ وْ أَ مَرَ بِالتَّقْوٰی أَرَأَ یْتَ إِنْ کَذَّبَ وَتَوَلّٰی} … "Have you seen the one who forbids a servant when he prays? Have you seen if he is upon guidance or enjoins righteousness? Have you seen if he denies and turns away?" Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: "By the One in Whose hand is my soul! If he had called his assembly, the mighty angels of Hell would have seized him."
