One Performing Salah (Prayer) Partially behind an Imam Who then Asks Him to Lead because of Losing his Wudu’

12. A group of our people has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah ibn Ayyub from al-Husayn ibn ‘Uthman from Sama‘ah from abu Basir from who has said the following: “I once asked him (the Imam) عليه السلام, about a man who performs Salah (prayer) with a people and he thinks it is the first (al-Dhuhr) but it is al-‘Asr. He (the Imam) said, ‘He considers it the first and perform al-‘Asr.’” In another Hadith it is said, ‘If he knows that it is al-‘Asr and has not performed the one before, he is not to join them.”’
