“Whoever fasts one day in the cause of Allah, Allah will keep the Fire away from his face the distance of seventy autumns (years) for that day.” (Using translation from Ibn Mājah 1717)
قَالَ رَسُولُ اللهِ ﷺ مَنْ صَامَ يَوْمًا فِي سَبِيلِ اللهِ بَاعَدَ اللهُ بِذَلِكَ الْيَوْمِ النَّارَ عَنْ وَجْهِهِ سَبْعِينَ خَرِيفًا
