"No man will enter the Fire who weeps for fear of Allah, Most High, until the milk goes back into the udders. And the dust (of Jihad) in the cause of Allah, and the smoke of Hell will never be combined." (Using translation from Nasāʾī 3108)
عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَلِجُ النَّارَ رَجُلٌ بَكَى مِنْ خَشْيَةِ اللهِ حَتَّى يَعُودَ اللَّبَنُ فِي الضَّرْعِ وَلَا يَجْتَمِعُ غُبَارٌ فِي سَبِيلِ اللهِ وَدُخَانُ نَارِ جَهَنَّمَ»
