Azaan-Call to Prayer

Call to prayer five times a day, usually by a muezzin from a minaret.
Saying the Azaan holds great benefits and reward as mentioned in the Ahadith.

1) The Prophet of Allah has said, "I went to paradise and saw domes of pearl and its dirt is of musk." He said, "Oh Gabrial, who is this for?" He replied, "This if for your ummah's Muazzin (one who says the Azaan) and Imams." [Rawahu Abu Ya'la Fee Musnad]
2) The one who says Azaan for Sawaab is like that martyred who is drenched in blood and when he will die insects will not come on in his body. [Rawahut Tabrani]
3) If people knew how much reward there was in Azaan then swords would be used amongst them [to say it]. (Rawahu Ahmad)
4) The duaa between Azaan and Iqamah is not rejected. [Abu Daood & Tirmizi]
