Origin of Islam

Narrated Anas bin Malik: The Prophet (peace be upon him) passed by a woman who was weeping beside a grave. He told her to fear Allah and be patient. She said to him, “Go away, for you have not been afflicted with a calamity like mine.” And she did not recognize him. Then she was informed that he was the Prophet. So she went to the house of the Prophet (peace be upon him) and there she did not find any guard. Then she said to him, “I did not recognize you.” He said, “Verily, the patience is at the first stroke of a calamity.”

- Sahih Al-Bukhari – Book 23 Hadith 372

Narrated Abu Said Al Khudri: Some Ansari persons asked for (something) from Allah’s Apostle and he gave them. They again asked him for (something) and he again gave them. And then they asked him and he gave them again till all that was with him finished. And then he said “If I had anything, I would not keep it away from you. (Remember,) whoever abstains from asking others, Allah will make him contented, and whoever tries to make himself self-sufficient, Allah will make him self-sufficient. And whoever remains patient, Allah will make him patient. Nobody can be given a blessing better and greater than patience.”

- Sahih Al-Bukhari – Book 24 Hadith 548
