Allah, The Most Exalted, says:
“By no means shall you attain the reality of true piety and righteousness, unless you spend (in Allah’s cause) that which you love “ (Quran-Ale-‘Imran 3: 92)
Jabir ibn ‘Abdullah Radiyallahu ‘anhuma narrates:
“Whenever Rasullullah Sallaliahu ‘alaihi wasallam was asked for anything, he never said ‘No’.”(Hadith-Muslim)
Note: It means that The Messenger of Allah (Sallaliahu ‘alaihi wasallam) never used the plain word ‘no’ before anyone who asked for something. If he had something with him, he would give it then and there; if not, he would either promise him, or remain quiet, or excuse himself with some suitable words, or say words of supplication.
A wise woman who was travelling in the mountains found a precious stone in a stream. The next day she met another traveller who was hungry, and the wise woman opened her bag to share her food. The hungry traveller saw the precious stone and asked the woman to give it to him. She did so without hesitation. The traveller left, rejoicing in his good fortune. He knew the stone was worth enough to give him security for a lifetime. But a few days later he came back to return the stone to the wise woman.
“I’ve been thinking,” he said, “I know how valuable the stone is, but I give it back in the hope that you can give me something even more precious. Give me what you have within you that enabled you to give me the stone.”
The Messenger of Allah Muhammad [Peace be upon him] is reported to have said: “Do not hoard; otherwise, Allah will withhold from you.’‘ [Al-Bukhari and Muslim].
