Narrated Khalid bin Al-Harith:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْوَهَّابِ ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ ، قَالَ سُئِلَ عُبَيْدُ اللَّهِ عَنِ الْمُحَصَّبِ، فَحَدَّثَنَا عُبَيْدُ اللَّهِ ، عَنْ نَافِعٍ ،، قَالَ نَزَلَ بِهَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَعُمَرُ وَابْنُ عُمَرَ. وَعَنْ نَافِعٍ أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ كَانَ يُصَلِّي بِهَا ـ يَعْنِي الْمُحَصَّبَ ـ الظُّهْرَ وَالْعَصْرَ ـ أَحْسِبُهُ قَالَ وَالْمَغْرِبَ. قَالَ خَالِدٌ لاَ أَشُكُّ فِي الْعِشَاءِ، وَيَهْجَعُ هَجْعَةً، وَيَذْكُرُ ذَلِكَ عَنِ النَّبِيِّ صلى الله عليه وسلم .
'Ubaidullah was asked about Al Mahassab. 'Ubaidullah narrated: Nafi` said, 'Allah's Messenger (ﷺ)s, `Umar and Ibn `Umar camped there." Nafi` added, "Ibn `Umar used to offer the Zuhr and `Asr prayers at it (i.e. Al-Mahassab)." I think he mentioned the Maghrib prayer also. I said, "I don't doubt about `Isha' (i.e. he used to offer it there also), and he used to sleep there for a while. He used to say, 'The Prophet (ﷺ) used to do the same.' "
