Imam Al-Nawawi’s Riyad-us-Saliheen
Chapter 63
Competition in matters of the Hereafter

Allah, the Exalted, says:

“Let (all) those strive who want to strive (i.e., hasten earnestly to the obedience of Allah).” (83:26)

569. Sahl bin Sa`d (May Allah be pleased with him) reported: A drink was brought to the Messenger of Allah (sallallaahu ’alayhi wa sallam) and he drank some of it. On his right was a boy and on his left were elderly people. He said to the boy, “Would you permit me to give the rest of this drink to these on my left?” The boy said, “O Messenger of Allah, I would certainly not give preference to anyone in anything that might come to me from you.” So he handed over the rest of the drink to him.
[Al-Bukhari and Muslim].

570. Abu Hurairah (May Allah be pleased with him) reported: The Prophet (sallallaahu ’alayhi wa sallam) said, “While Ayyub (sallallaahu ’alayhi wa sallam) the Prophet was taking a bath, naked, a large number of gold locusts fell on him. He tried to collect them in a piece of cloth, when he heard his Rubb (Allah) calling him: `O Ayyub ! Have I not sufficed you to care for what you see (the worldly possessions)?’ Ayyub (sallallaahu ’alayhi wa sallam) said: `Indeed by Your Power, but I can never do away with Your Blessings.”’
