Musannaf Ibn Abi Shaybah 13192 — A person in ihram clipping his nail

Muhammad bin Abdullah bin Abi Maryam said: I was in the state of ihram when my nail began to hurt me, so I cut it. Then I asked Sa'id bin Jubayr, and he asked, "Was it hurting you?" I said, "Yes." He said, "Then cut it, O son of my brother. Allah says: 'Allah intends ease for you and does not intend hardship for you.' [Al-Baqarah: 185]"
