Read and reflect on verse 5235 from Surah At-Tahrim: O YOU who have attained to faith! Ward off from yourselves and those who are close to you that fire [of the hereafter] whose fuel is human beings and ...
يَا أَيُّهَا الَّذِينَ آمَنُوا قُوا أَنْفُسَكُمْ وَأَهْلِيكُمْ نَارًا وَقُودُهَا النَّاسُ وَالْحِجَارَةُ عَلَيْهَا مَلَائِكَةٌ غِلَاظٌ شِدَادٌ لَا يَعْصُونَ اللَّهَ مَا أَمَرَهُمْ وَيَفْعَلُونَ مَا يُؤْمَرُونَ
O YOU who have attained to faith! Ward off from yourselves and those who are close to you that fire [of the hereafter] whose fuel is human beings and stones: [lording] over it are angelic powers awesome [and] severe, who do not disobey God in whatever He has commanded them, but [always] do what they are bidden to do.
