Ata' bin Abi Rabah said: I saw Abdullah bin Umar (may Allah be pleased with them both) performing tawaf after the morning prayer, before sunrise; then he prayed. The narrator says: I mentioned this to Nafi' (may Allah have mercy on him), and Nafi' (may Allah have mercy on him) said: The people of Makkah have made a mistake about Ibn Umar (may Allah be pleased with them both).
This rejection by Nafi' (may Allah have mercy on him) is not accepted, because he did not know about its reliability. As for what the people of Makkah narrate from Ibn Umar (may Allah be pleased with them both), had he known, he would have confirmed it, not rejected it. Ibn Umar (may Allah be pleased with them both) used to pray the funeral prayer after Asr and after the morning prayer, and likewise the two rak'ahs of tawaf; but in his view prayer is prohibited at the time of sunrise and sunset. And what the people of Makkah narrate from him may be in accordance with his own view. (And Allah knows best.)
