It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said: When the surah 'Idha ja'a nasru Allahi wa al-fath' (al-Nasr) was revealed, at the time of its revelation the Messenger of Allah (peace and blessings be upon him) was informed of his (approaching) death, so he (peace and blessings be upon him) began to strive and exert himself in the matter of the Hereafter far more than before.
Then after that the Messenger of Allah (peace and blessings be upon him) said: "The help of Allah has come, victory has been granted, and the people of Yemen have come." A man said: O Messenger of Allah! Who are the people of Yemen? He (peace and blessings be upon him) said: "They are a people whose hearts are very tender and whose natures are very gentle; faith is Yemeni and understanding (fiqh) is Yemeni."
