Explanation & Benefits
Hafiz Abdush Shakoor Tirmidhi
Benefits: It is understood that performing ablution (wudu) is not obligatory for eating food. And it is also understood that one should not impose restrictions upon oneself that the Shari‘ah has not imposed. Remaining in a state of ablution at all times is good, but it is not obligatory. It is obligatory for prayer (salah).
