Muwatta Malik, Book 15, Hadith 474 (In-Book) ⓘ

Yahya related to me from Malik from Ayyub ibn Abi Tamima as- Sakhtayani from Muhammad ibn Sirin that Umar ibn al-Khattab was with some people who were reciting Qur'an. He went to relieve himself and then came back and recited Qur'an. One of the men said to him, "Amir al muminin, are you reciting the Qur'an without being in wudu?" Umar replied, "Who gave you a verdict on this? Was it Musaylima?"'

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَيُّوبَ بْنِ أَبِي تَمِيمَةَ السَّخْتِيَانِيِّ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، كَانَ فِي قَوْمٍ وَهُمْ يَقْرَءُونَ الْقُرْآنَ فَذَهَبَ لِحَاجَتِهِ ثُمَّ رَجَعَ وَهُوَ يَقْرَأُ الْقُرْآنَ فَقَالَ لَهُ رَجُلٌ يَا أَمِيرَ الْمُؤْمِنِينَ أَتَقْرَأُ الْقُرْآنَ وَلَسْتَ عَلَى وُضُوءٍ فَقَالَ لَهُ عُمَرُ مَنْ أَفْتَاكَ بِهَذَا أَمُسَيْلِمَةُ
