fasting
4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُوسَى بْنِ سَعْدَانَ عَنْ عَبْدِ الله بْنِ الْهَيْثَمِ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) يَقُولُ لا تُلْزِقْ ثَوْبَكَ إِلَى جَسَدِكَ وَهُوَ رَطْبٌ وَأَنْتَ صَائِمٌ حَتَّى تَعْصِرَهُ.
4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Musa ibn Sa‘dan from ‘Abd Allah ibn al-Haytham from ‘Abd Allah ibn Sinan who has said the following: “I once heard abu ‘Abd Allah (a.s.), say, ‘You must not attach your wet clothes to your body, when you are fasting, before you wring them.’”
