Hadith 20:4
Sahih (Darussalam)
It was narrated from Bahz bin Hakim, from his father, from his grandfather that the Messenger of Allah (ﷺ) said:
“Allah (SWT) will not accept any good deed from a polytheist who committed polytheism after having become Muslim, until he leaves the polytheists and joins the Muslims.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بَهْزِ بْنِ حَكِيمٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَقْبَلُ اللَّهُ مِنْ مُشْرِكٍ أَشْرَكَ بَعْدَ مَا أَسْلَمَ عَمَلاً حَتَّى يُفَارِقَ الْمُشْرِكِينَ إِلَى الْمُسْلِمِينَ "
