وَعَنِ ابْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا فِي قَوْلِهِ عَزَّ وَجَلَّ ﴿
وَإِنْ كُنْتُمْ مَرْضَى أَوْ عَلَى سَفَرٍ ﴾ قَالَ: «إِذَا كَانَتْ بِالرَّجُلِ اَلْجِرَاحَةُ فِي سَبِيلِ اَللَّهِ وَالْقُرُوحُ، فَيُجْنِبُ، فَيَخَافُ أَنْ يَمُوتَ إِنْ اِغْتَسَلَ: تَيَمَّمَ»
concerning the verse, “And if you are ill or on a journey…” (an-Nisa: 43). He said, “If a man sustains a wound, which he suffered during Jihad (in the cause of Allah) or ulcers, then he became junub (sexually impure) and is afraid that if he bathes he would die; he may perform ablution with clean earth (Tayammum).”
