[Machine] The Prophet ﷺ said, "Whoever eats clay, it is as if he is helping to kill himself." Abu Ahmad said, "I do not know anyone who narrates this except Suhail ibn Abi Salih, other than Abdul Malik, and he is unknown." The sheikh said, "If this is authentic, it does not indicate prohibition, but rather discouragement from consuming it excessively. Excessive consumption, whether of clay or other substances, that harms the body, is prohibited. And Allah knows best."  

قَالَ النَّبِيُّ ﷺ مَنْ أَكَلَ الطِّينَ فَكَأَنَّمَا أَعَانَ عَلَى قَتْلِ نَفْسِهِ قَالَ أَبُو أَحْمَدَ وَهَذَا لَا أَعْلَمُ يَرْوِيهِ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ غَيْرَ عَبْدِ الْمَلِكِ هَذَا وَهُوَ مَجْهُولٌ قَالَ الشَّيْخُ وَهَذَا لَوْ صَحَّ لَمْ يَدُلَّ عَلَى التَّحْرِيمِ وَإِنَّمَا دَلَّ عَلَى كَرَاهِيَةِ الْإِكْثَارِ مِنْهُ وَالِإكْثَارُ مِنْهُ وَمِنْ غَيْرِهِ حَتَّى يَضُرَّ بِبَدَنِهِ مَمْنُوعٌ وَاللهُ أَعْلَمُ
