Hawzah News Agency – Prophet Jesus peace be upon him says:
يا عَبيدَ السّوءِ، تَلومونَ النّاسَ عَلَى الظَّنِّ، ولا تَلومونَ أنفُسَكُم عَلَى اليَقينِ؟!
‘O iniquitous servants, you blame others based on what you conjecture about them and do not blame yourselves in that which you know for certain [of your own wrong doings]?!’
