(who is ʿAbdur-Rahman bin Jabir) Messenger of Allah ﷺ said," Anyone whose both feet get covered with dust in Allah's Cause will not be touched by the (Hell) fire."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَا اغْبَرَّتْ قَدَمَا عَبْدٍ فِي سَبِيلِ اللَّهِ فَتَمَسَّهُ النَّارُ  

[Machine] The Messenger of Allah ﷺ said, "The smoke of Hellfire and dust on the path of Allah do not combine in the respiratory system of a Muslim."  

قَالَ رَسُولُ اللَّهِ ﷺ «لَا يَجْتَمِعُ دُخَانُ جَهَنَّمَ وَغُبَارٌ فِي سَبِيلِ اللَّهِ فِي مَنْخَرَيْ مُسْلِمٍ»  

"The dust in the cause of Allah, the Mighty and Sublime, and the smoke of Hell will never be combined in the nostrils of a Muslim." (Using translation from Nasāʾī 3113)  

عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَجْتَمِعُ غُبَارٌ فِي سَبِيلِ اللهِ وَدُخَانُ جَهَنَّمَ فِي مِنْخَرَيْ مُسْلِمٍ أَبَدًا»  

"لَا يَجْتَمِعُ غُبَارٌ في سبيلِ الله ودُخَانُ جَهَنَّم في مِنْخَرىْ مُسْلِم أَبَدًا".
