Islam urges the Muslim to regularly pray in congregation in the mosques, but if it is difficult to attend the prayer in congregation, then Islam grants a concession allowing the Muslim not to pray in congregation. The types of excuses allowing that include severe cold and rain. This hadith highlights that, as Nafi‘, the freed slave of Ibn ‘Umar, narrates that Ibn ‘Umar gave the call to prayer on an extremely cold night in Dajnan, which is a mountain in Tihamah, twenty-five miles from Makkah. Then Ibn ‘Umar (may Allah be pleased with him) said, straight after giving the adhan: Pray where you are; that is, in the places where you are staying and your tents. And he told him that this was the practice of the Messenger of Allah (blessings and peace of Allah be upon him), as he would instruct a mu’adhdhin to give the adhan, then say straight after finishing the adhan: Ala sallu fi’l-rihal (Attention! Pray where you are). That would be on a cold or very rainy night, whilst travelling. The apparent meaning of the report is that this concession is only for travel, but the scholars stated that this concession is general and also applies to anyone who is not travelling but could find it difficult to attend the prayer in congregation. This report states that when this phrase, “Sallu fi rihalikum (pray where you are)” is to be said is immediately after finishing the adhan. In al-Sahihayn it is narrated in the hadith of Ibn ‘Abbas that it is to be said in place of the phrases Hayya ‘ala al-salah and Hayya ‘ala al-falah. Whichever of the two options the caller chooses, there is nothing wrong with it. This hadith highlights the kindness of Allah (may He be glorified and exalted), and how He makes things easy for His slaves. It also indicates that it is prescribed to stay away from attending prayers in congregation when there is fear of harm that could result from that..
