Hadith Section/Book: Sahih Bukhari Sahih Bukhari Book 60. Prophetic Commentary on the Qur'an (Tafseer of The Prophet (PBUH))
Narrated By Anas bin Malik : Abu Jahl said, "O Allah! If this (Qur'an) is indeed the Truth from You), then rain down on us a shower of stones from the sky or bring on us a painful punishment." So there was revealed: 'But Allah would not punish them while you (Muhammad) were amongst them, nor will He punish them while they seek (Allah's) Forgiveness. And why Allah should not punish them while they stop (men) from Al-Masjid-al-Haram...' (8.33-34)
