"Abdullah bin Umar came to me when I had stopped beneath a large tree on the way to Makkah. He said: 'Why did you stop beneath this tree?' I said: 'Because of its shade.' Abdullah said: 'The Messenger of Allah said: If you are between the two mountains of Mina - and he pointed with his hand toward the east - there is a valley there called As-Surrabah according to the narration of Al-Harith: Called As-Surar - in which there is large tree beneath which seventy prophets were born." (Daif)  

مَا أَنْزَلَكَ تَحْتَ هَذِهِ الشَّجَرَةِ فَقُلْتُ أَنْزَلَنِي ظِلُّهَا قَالَ عَبْدُ اللَّهِ فَقَالَ رَسُولُ اللَّهِ ﷺ إِذَا كُنْتَ بَيْنَ الأَخْشَبَيْنِ مِنْ مِنًى وَنَفَخَ بِيَدِهِ نَحْوَ الْمَشْرِقِ فَإِنَّ هُنَاكَ وَادِيًا يُقَالُ لَهُ السُّرَّبَةُ وَفِي حَدِيثِ الْحَارِثِ يُقَالُ لَهُ السُّرَرُ بِهِ سَرْحَةٌ سُرَّ تَحْتَهَا سَبْعُونَ نَبِيًّا  

The Messenger of Allah addressed us in Mina, and Allah enabled us to hear hwat he said when we were in our encampments. The Prophet started to teach them their rituals until he reached the Himar (Stoning the pillars), and he said: look for pebbles the size of date stones or fingertips. And he told the Muhajirun to camp in front of the Masjid and the Ansar to camp behind the Masjid.  

خَطَبَنَا رَسُولُ اللَّهِ ﷺ بِمِنًى فَفَتَحَ اللَّهُ أَسْمَاعَنَا حَتَّى إِنْ كُنَّا لَنَسْمَعُ مَا يَقُولُ وَنَحْنُ فِي مَنَازِلِنَا فَطَفِقَ النَّبِيُّ ﷺ يُعَلِّمُهُمْ مَنَاسِكَهُمْ حَتَّى بَلَغَ الْجِمَارَ فَقَالَ بِحَصَى الْخَذْفِ وَأَمَرَ الْمُهَاجِرِينَ أَنْ يَنْزِلُوا فِي مُقَدَّمِ الْمَسْجِدِ وَأَمَرَ الأَنْصَارَ أَنْ يَنْزِلُوا فِي مُؤَخَّرِ الْمَسْجِدِ
