وَنُدِبَ تَأْخِيرُ التَّيَمُّمِ لِمَنْ يَرْجُو الْمَاءَ قَبْلَ خُرُوجِ الْوَقْتِ، وَيَجِبُ التَّأْخِيرُ بِالْوَعْدِ بِالْمَاءِ وَلَوْ خَافَ الْقَضَاءَ
• If a person reasonably hopes water will become available before the prayer time ends, delaying Tayammum is recommended.
• If a reliable promise of water is made, the text raises the delay to obligatory even if there is fear that the prayer will become Qada.
• A promise of clothing or a water-container/tool also has a separate delay rule in the text when Qada is not feared.
