Muwatta Imam Malik Book of Hajj, Hadith 226
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "The jamras should not be stoned during the three days until after the sun has passed the meridian."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَقُولُ لاَ تُرْمَى الْجِمَارُ فِي الأَيَّامِ الثَّلاَثَةِ حَتَّى تَزُولَ الشَّمْسُ .
