By His Grace and Mercy, Allah has made embracing Islam a cause to erase the sins that were committed before it. When a disbeliever becomes Muslim, Allah forgives all that he did when he was a non-Muslim, and he becomes cleansed of sin.

When you enter the mosque, you should not sit down until you have prayed two Rak`ahs to “greet the mosque”. 5.

The duties of Muslims towards non-Muslims include: 1- calling them to Islam; 2- not wronging them; 3- being good neighbours to them; and 4- giving them charity not Zakah if they are poor. There is nothing wrong with interacting with non-Muslims such as buying, selling, renting, hiring and so on. Muslims should not partake in celebrating non-Muslim festivals, but are allowed to offer condolences if their loved one dies.

The wisdom behind purification in Islam includes: 1. Purification is in harmony with the sound nature (fitrah) that Allah, may He be exalted, instilled in people. 2. Islam is a religion of cleanliness and beauty, and it encourages its followers to stand out among other people by cleaning their bodies, combing their hair, wearing the purest of clothes and smelling good. 3. Modern, well-founded scientific studies have proven that cleanliness and purification protect a person from many diseases, and that filth is the cause of many diseases. 4. The Muslim is required to meet and converse with his Lord, may He be exalted [in prayer]. 5. Whoever strives to purify his body and clothes from filth and impurities should be even keener to purify his heart and soul of bad characteristics.
