English explanation:
- (Yusuf Ali): But ye turned back thereafter: Had it not been for the Grace and Mercy of Allah to you, ye had surely been among the lost.
- (Marmaduke Pickthall): Then, even after that, ye turned away, and if it had not been for the grace of Allah and His mercy ye had been among the losers.
(pick any, you may paraphrase and you don't have to recite it verbatim)
ثُمَّ تَوَلَّيْتُم مِّنۢ بَعْدِ ذَٰلِكَ فَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ لَكُنتُم مِّنَ ٱلْخَٰسِرِينَ
Thumma tawallaytum min baAAdi thalika falawla fadlu Allahi AAalaykum warahmatuhu lakuntum mina alkhasireena
