"The final words of the Adhan are: 'Allahu Akbar, Allahu Akbar; La ilaha illallah (Allah is the Greatest, Allah is the Greatest, there is none worthy of worship except Allah.)'"
"The final words of the Adhan of Bilal were: 'Allahu Akbar, Allahu Akbar, Allahu Akbar; La ilaha illallah (Allah is the Greatest, Allah is the Greatest, there is none worthy of worship except Allah.)'"

"The Messenger of Allah (S.A.W) traveled until he came to 'Arafah, where he found that the tent had been pitched for him in Namirah, so he stopped there.

Then Bilal called the Adhan, then he said the Iqamah and he prayed Zuhr, then he said the Iqamah and prayed 'Asr, and he did not offer any prayer in between them."
