وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ اللَّهَ يَقْبَلُ تَوْبَةَ الْعَبْدِ مَا لَمْ يُغَرْغِرْ» . رَوَاهُ التِّرْمِذِيُّ وَابْن مَاجَه

Ibn ‘Umar reported God’s messenger as saying, “God accepts a servant’s repentance till he gives up his spirit in death.”* *The Arabic is ma lam yugharghir , which might, be translated literally “as long as he has not died with the death rattle in his throat.” Tirmidhi and Ibn Majah transmitted it.
