In the Kitaab ‘Riyaadhus Saaliheen’ authored by Imam Nawawi (رحمة الله عليه ) , Imam Saheb has dedicated an entire chapter regarding moderation in ‘Ibaadah . (Not imposing hardships on one’s self etc …)
Narrated by Abu Juhaifah (رضي الله عنه)
The Prophet ﷺ made a bond of brotherhood between Salman and Abu Darda رضي الله عنهما .
Salman رضي الله عنه paid a visit to Abu Darda ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ and found Um Ad-Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨها dressed in shabby
clothes . He asked her why she was in that state. She replied, “Your brother Abu
Ad-Darda’ is not interested in (the luxuries of) this world. He has not slept on our bed nor uncovered our veil .”
In the meantime Abu Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ came and prepared a meal for Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ . Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ requested Abu Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ to eat (with him), but Abu Ad-Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ said, “I am fasting.”
Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ said, “I am not going to eat unless you eat.” So, Abu Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ ate. When it was night and (a part of the night passed), Abu Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ got up (to offer the
night prayer), but Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ told him to sleep and Abu Ad-Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ slept. After
sometime Abu Ad-Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ again got up but Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ told him to sleep. When it was the last hours of the night, Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ told him to get up then, and both of them
offered the prayer. Salman ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ told Abu Ad-Darda’, “Your Lord has a right on you, your
body has a right on you, and your family (wife and children) have right on you; so you should give the
rights of all those who has a right on you.” Abu Ad-Darda’ ﺭﺿﻲ ﺍﻟﻠﻪ ﻋﻨﻪ came to the Prophet ﷺ
and narrated the whole story. The Prophet ﷺ said, “Salman has spoken the truth.”
In many other Ahaadith under this chapter the words ‘ ان لجسدك عليك حق ، ان لعىنك عليك حق ، ‘ etc … meaning ‘surely for your body there is a right , surely for your eyes there is a right’
In another Hadith – it states that if you are tired and you are performing Salaah etc then you should sleep because you don’t know what you will curse or say to yourself due to tiredness ..
Another Hadith says that those who impose hardships on themselves will be destroyed .
All these Ahaadith fall in Chapter 14 of Riyaadhus Saaliheen .
The Ahaadith are not proper literal meaning – rather I’d say they are ‘something to the effect ..’
