عَنْ عَائِشَةَ قَالَتْ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَطْيَبَ مَا أَكَلْتُمْ مِنْ كَسْبِكُمْ وَإِنَّ أَوْلَادَكُمْ مِنْ كَسْبِكُمْ» . رَوَاهُ التِّرْمِذِيُّ وَالنَّسَائِيُّ وَابْنُ مَاجَهْ. وَفِي رِوَايَةِ أَبِي دَاوُدَ وَالدَّارِمِيِّ: «إِنَّ أَطْيَبَ مَا أَكَلَ الرَّجُلُ مِنْ كَسْبِهِ وَإِنَّ وَلَده من كَسبه»

Jabir reported God’s Messenger as saying, “Flesh which has grown out of what is unlawful will not enter paradise*, but hell is more fitting for all flesh which has grown out of what is unlawful.” Ahmad, Darimi, and Baihaqi, in Shu'ab al-iman, transmitted it.*The reference here is to people who live on unlawful source of income.
