وَعَن الْمُهلب
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنْ بَيَّتَكُمُ الْعَدُوُّ فَلْيَكُنْ شِعَارُكُمْ: حم لَا ينْصرُونَ»
Al-Muhallab reported God’s Messenger as saying, “If the enemy attacks you at night let your war-cry be Ha Mim. They will not be helped.”* *These words may be taken from sura 41 which is one beginning with Ha Mim. The other words are in verse 16 of that sura. Cf. 44: 41.
