The Messenger of allah said: "Whoever catches up (with Fajir prayer) in Jam (Al-Muzdalifah) with the Imam and the people (and stays there) until they move on, the he has caught up with Hajj. Whoever does not catuch up with the people and the Imam, then has not caught it (Hajj).'"  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَدْرَكَ جَمْعًا مَعَ الإِمَامِ وَالنَّاسِ حَتَّى يُفِيضَ مِنْهَا فَقَدْ أَدْرَكَ الْحَجَّ وَمَنْ لَمْ يُدْرِكْ مَعَ النَّاسِ وَالإِمَامِ فَلَمْ يُدْرِكْ  

[Machine] He came to the Prophet Muhammad ﷺ and said, "O Messenger of Allah, I have become tired, I am thirsty, and I have become exhausted." The Messenger of Allah ﷺ said, "Whoever reaches the gathering with the people and the imam before they disperse, then he has performed the Hajj (pilgrimage), and whoever does not reach the people and the imam in a gathering until they disperse, then he has not performed the Hajj."  

أَنَّه أَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَتْعَبْتُ وَأَنْصَبْتُ وأَحْفَيْتُ فَقَالَ رَسُولُ اللهِ ﷺ «مَنْ أَدْرَكَ جَمْعًا مَع النَّاسِ والْإِمامَ قَبْلَ أَنْ يُفِيضُوا فَقَدْ أَدْرَكَ الْحَجَّ وَمَنْ لَم يُدْرِكْ النَّاسَ والإِمامَ بِجَمْعٍ حَتَّى يُفِيضُوا فَلَم يُدْرِكِ الْحَجَّ»  

The Messenger of allah said: "Whoever catches up (with Fajir prayer) in Jam (Al-Muzdalifah) with the Imam and the people (and stays there) until they move on, the he has caught up with Hajj. Whoever does not catuch up with the people and the Imam, then has not caught it (Hajj).'" (Using translation from Nasāʾī 3040)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ أَدْرَكَ جَمْعًا مَعَ الْإِمَامِ وَالنَّاسِ حَتَّى يُفِيضُوا فَقَدْ أَدْرَكَ الْحَجَّ وَمَنْ لَمْ يُدْرِكْ مَعَ النَّاسِ وَالْإِمَامِ فَلَمْ يُدْرِكْ»
