The Ruling on Praying Without the Adhan and Iqamah

This message is from Mahdi Ayal, also from the same sender. It is a message from the same sender, but since we have reviewed his first message, we will review his second one. He says: My question is: Is the adhan obligatory in prayer? Does leaving it out diminish the prayer? And is it required for an individual praying alone to call the adhan for his prayer?
Answer: The adhan is a collective obligation (fard kifayah) in prayer. It is obligatory for the congregation, whether in a settled place or traveling, that they call the adhan; one of them calls the adhan and another gives the iqamah. This is the correct view: that both the adhan and the iqamah are a collective obligation. If one person from the congregation, whether in a village or while traveling, performs them, it suffices for the rest. However, they are not a condition for the validity of the prayer, but rather they are obligatory as a collective obligation outside the prayer. So, whoever performs them has done well and will be rewarded, and whoever leaves them out has sinned, but the prayer is valid. Its validity does not depend on the adhan and iqamah; rather, the prayer is valid, but it is incomplete. If one intentionally prays without the adhan and without the iqamah, it is incomplete, the reward is diminished, and the prayer of one who prays with the adhan and iqamah is more complete and better.
It is not permissible for Muslims to intentionally leave out the adhan and iqamah. Rather, it is obligatory for one of the present congregation who is qualified for it, who is known for his justice, and who establishes the adhan, to call the adhan. One of them should call the adhan if he has this quality, meaning he establishes the adhan with its words and is known for his justice. Then he is relied upon for the adhan. He should be known for his apparent justice and should be one who establishes the adhan. He is the one who calls the adhan, whether in a settled place or while traveling.
As for if he is a single person traveling, it is better for him to call the adhan as well. As for whether it is obligatory upon him, there is disagreement and consideration in this matter. But the best and most preferable in every situation, and the Sunnah for him, is to call the adhan. This is based on what came in the hadith of Abu Sa'id al-Khudri (may Allah be pleased with him) : that he said: “... a man, when you are with your sheep ... raise your voice with the call, for no stone or tree hears the voice of the mu'adhdhin but it will testify for him on the Day of Resurrection. I heard it from your Prophet (peace and blessings be upon him).” So he commanded him to call the adhan while he was alone, which indicates its emphasis for the single person. As for whether it is obligatory upon him or not, it is a matter of disagreement and consideration. But he should not leave out the adhan. As for if they are a congregation, it is obligatory upon them to call the adhan; one of them calls the adhan and they give the iqamah as well. Yes.
