1ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنِ الْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ سَمِعْتُهُ يَقُولُ إِذَا لَمْ تَجِدْ مَاءً وَأَرَدْتَ التَّيَمُّمَ فَأَخِّرِ التَّيَمُّمَ إِلَى آخِرِ الْوَقْتِ فَإِنْ فَاتَكَ الْمَاءُ لَمْ تَفُتْكَ الأرْضُ.
1. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I heard him (the Imam) (a.s.), say, ‘If you cannot find water and you decide for Tayammum, you must wait until the time (for Salah (prayer)) is about to end. If water is still not available, you do not miss the soil and the ground.’”
