وَعَن الْمُهلب أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:
" إِنْ بَيَّتَكُمُ الْعَدُوُّ فَلْيَكُنْ شِعَارُكُمْ: حم لَا ينْصرُونَ ". رَوَاهُ التِّرْمِذِيّ وَأَبُو دَاوُد
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. Tirmidhi and Abu Dawud transmitted it.
