1. Namaz (salah) and Hajj are two of the most important pillars of Islam. Namaz involves praying at prescribed times in a specific manner to remember Allah, while Hajj refers to pilgrimage to Mecca at least once in a lifetime if one is able to do so.
2. It is recommended that every mentally and physically capable Muslim perform Hajj once in their lifetime. After performing Hajj, one should try to perform Umrah.
3. The Prophet Muhammad performed Hajj four times in his lifetime, with one Umrah performed each year other than the year of his final Hajj.
