عَنْ جَابِرٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَمَّا أَرَادَ الْحَجَّ أَذَّنَ فِي النَّاسِ فَاجْتَمَعُوا فَلَمَّا أَتَى الْبَيْدَاءَ أَحْرَمَ. رَوَاهُ البُخَارِيّ

Jabir said that when God’s messenger intended to perform the pilgrimage he made proclamation among the people and they assembled. Then when he came to al-Baida’ (a place near Dhul Hulaifa) he put on the ihram. Bukhari transmitted it.
