Hadith #509170

Yahya related to me from Malik that he had heard that Umar ibn al-Khattab used to stop at the first two jamras for such a long time that someone standing up would get tired.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، كَانَ يَقِفُ عِنْدَ الْجَمْرَتَيْنِ الأُولَيَيْنِ وُقُوفًا طَوِيلاً حَتَّى يَمَلَّ الْقَائِمُ ‏.‏
