حَدَّثَنَا مُوسَى، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ كَثِيرٍ أَبِي مُحَمَّدٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَجْلاَنَ قَالَ: مَرَّ عُمَرُ بْنُ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ بِرَجُلَيْنِ يَرْمِيَانِ، فَقَالَ أَحَدُهُمَا لِلْآخَرِ: أسَبْتَ، فَقَالَ عُمَرُ: سُوءُ اللَّحْنِ أَشَدُّ مِنْ سُوءِ الرَّمْيِ.
It is narrated from Abdur Rahman bin Ajlan (may Allah have mercy on him) that Sayyiduna Umar (may Allah be pleased with him) passed by two men who were shooting arrows. One of them said to the other: "Asbat," meaning "You hit the mark" (although it should be "Asabta"). Sayyiduna Umar (may Allah be pleased with him) said: A mistake in pronunciation is worse than a mistake in archery.
