Muwatta Imam Malik Book of Hajj, Hadith 221

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to stop for a long time at the first two jamras saying, "Allah is greater", "Glory be to Allah", "Praise be to Allah", and making duas to Allah, but he did not stop at the jamrat al-Aqaba.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَقِفُ عِنْدَ الْجَمْرَتَيْنِ الأُولَيَيْنِ وُقُوفًا طَوِيلاً يُكَبِّرُ اللَّهَ وَيُسَبِّحُهُ وَيَحْمَدُهُ وَيَدْعُو اللَّهَ وَلاَ يَقِفُ عِنْدَ جَمْرَةِ الْعَقَبَةِ .
