إِنۡ أَرَادَ بِكُمۡ سُوۤءًا أَوۡ أَرَادَ بِكُمۡ رَحۡمَةࣰۚ

وَلَا یَجِدُونَ لَهُم مِّن دُونِ ٱللَّهِ 
وَلِیࣰّا وَلَا نَصِیرࣰا

اگر خدا تمہارے ساتھ 
برائی کا ارادہ کرے 
تو کون تم کو 
اس سے بچا سکتا ہے 
یا اگر تم پر 
مہربانی کرنی چاہے

اور یہ لوگ 
خدا کے سوا 
کسی کو 
نہ اپنا دوست پائیں گے 
اور نہ مددگار
