Mishkat al-Masabih #594

Anas said they mentioned kindling fire and the use of a bell, and mentioned the Jews and the Christians. Then Bilal was ordered to repeat the call to prayer twice and the statement that the time for prayer had come (al-iqama) once. Isma'il1 said that he mentioned it to Ayyub,2 and he said it was correct except regarding the iqama. (Bukhari and Muslim.) 1. Bukhari (Adhan, 3) gives a shorter form of the tradition than that above, mentioning Ismail b. Ibrahim in his isnad and telling how he made the enquiry of Ayyub. 2. Ayyub b. Abu Tamima.
