عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ مَنِ اشْتَرَى ثَوْبًا بِعَشَرَةِ دَرَاهِمَ وَفِيهَا دِرْهَمٌ حَرَامٌ لَمْ يَقْبَلِ اللَّهُ لَهُ صَلَاةً مَا دَامَ عَلَيْهِ قَالَ ثُمَّ أَدْخَلَ إِصْبَعَيْهِ فِي أُذُنَيْهِ وَقَالَ صُمَّتَا إِنْ لَمْ أَكُنْ سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُهُ
It is narrated from Sayyiduna Abdullah bin Umar, may Allah be pleased with them both, who says: If a man buys a garment for ten dirhams and one dirham of it is from unlawful earnings, then as long as that cloth remains on his body, Allah Almighty will not accept his prayer. Then Sayyiduna Ibn Umar, may Allah be pleased with them both, put both his fingers in his ears and said: If I have not heard this from the Messenger of Allah, peace and blessings be upon him, then may both my ears become deaf.
