Perform ablution properly and sniff water up into your nostrils thoroughly when not fasting.

Ablution is an important part of Islamic practice and is a ritual washing performed by Muslims before prayer. It involves washing the face, arms, head and feet with water. The Prophet Muhammad (PBUH) also taught that when performing ablution, one should sniff water up into their nostrils thoroughly unless they are fasting. This teaches us to be mindful of our actions and to take care in how we perform our religious duties. It also reminds us that even small acts can have great significance in our faith.
