مَّا يُقَالُ لَكَ إِلَّا مَا قَدْ قِيلَ لِلرُّسُلِ مِن قَبْلِكَ ۚ إِنَّ رَبَّكَ لَذُو مَغْفِرَةٍ وَذُو عِقَابٍ أَلِيمٍ (43)
(41:43) (O Prophet), nothing is said to you but what was already said to the Messengers before you. Surely your Lord is the Lord of forgiveness *53 and the Lord of grievous chastisement.
*53) That is, "It is all due to His clemency and forgiveness that although His Messengers were opposed, abused and persecuted yet He went on giving respite to their opponents for years and years on end. "
