Volume 4, Book 52, Number 101 :
Narrated by Malik bin Al-Huwairith (radiallaahu `anhu)
On my departure from the Prophet (sallallaahu `alayhi wasallam) he said to me and to a friend of mine, “You two, pronounce the Adhan and the Iqama for the prayer and let the elder of you lead the prayer.”
We’ve established previously that the minimum number of people required for a congregational prayer is two. This hadith further proves the importance of the adhaan and iqaamah regardless of the number of people in congregation and the place. Adhaan and iqaamah are NOT limited to the mosque, they should be established wherever the congregation is being held – even while traveling.
While looking up the importance of adhaan and iqaamah, I came across this absolutely beautiful hadeeth of ‘Uqbah ibn ‘Aamir, who said that the Prophet (peace and blessings of Allaah be upon him) said:
‘Your Lord likes it when a shepherd at the top of a mountain pass calls the Adhaan for prayer and then prays. Then Allaah says, “Look at this slave of mine, saying the Adhaan and the Iqaamah for prayer and fearing Me. I ask you to bear witness that I have forgiven My slave and will admit him to Paradise.”’” (Narrated by al-Nisaa’i)
This is just too good to ignore. Such beautiful rewards for an easy act. It also proves the importance of adhaan and iqaamah for a person who’s praying alone (men only). Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allah have mercy on him) said in reply to a related question:
The Sunnah is to give the adhaan and iqaamah. As to whether it is obligatory, there is a difference of opinion among the scholars. It is better and more on the safe side for you to give the adhaan then the iqaamah, because of the general meaning of the evidence. But you should pray in congregation whenever possible. If there is a congregation or you can hear the call to prayer from a mosque near you, then it is obligatory for you to respond to the muezzin and attend the prayer in congregation. If you cannot hear the call and there is no mosque near you, the Sunnah is for you to give the adhaan yourself, then the iqaamah. End quote.
Al-Shaafa’i (may Allaah have mercy on him) said:
“If a man neglects to say the Adhaan and Iqaamah when he is praying alone or in congregation, I regard that as makrooh, but he does not have to repeat the prayers he did without the Adhaan or Iqaamah.”
