To Convince Someone of His Mistake

The shaikh, Dr. Muḥammad ibn Ghālib Al-ʿUmarī, may Allāh protect him, said:

Among the hardest things to convince others of are mistakes they’ve fallen into, even if [their mistake] were clear and obvious. That’s why not paying them any more heed—after making things clear [to them] and conveying [the truth]—and [instead] paying attention to fixing [one’s own] soul and making sure it’s upon right guidance is the way that’s more correct.

And it’s with the like of this that we understand His, the All-High’s, saying:

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ عَلَيۡكُمۡ أَنفُسَكُمۡۖ لَا يَضُرُّكُم مَّن ضَلَّ إِذَا ٱهۡتَدَيۡتُمۡۚ إِلَى ٱللَّهِ مَرۡجِعُكُمۡ جَمِيعَا فَيُنَبِّئُكُم بِمَا كُنتُمۡ تَعۡمَلُونَ

O you are upon [Islamic] faith [in your hearts, your words, and your deeds], hold yourselves firmly [to obeying Allāh and avoiding all that He has prohibited, even if others do not respond to you]; those who have gone astray will not harm you [with their having gone astray] if you hold on to guidance. To Allāh you will all be returned [in the Hereafter], and then He will tell you about your actions [and pay you back for them]. (Al-Māʾidah, 105)
