Narrated Qurra bin Khalid:
Once he waited for Al-Hasan and he did not show up till it was about the usual time for him to start his speech; then he came and apologized saying, “Our neighbors invited us.” Then he added, “Narrated Anas, ‘Once we waited for the Prophet till it was midnight or about midnight. He came and led the prayer, and after finishing it, he addressed us and said, ‘All the people prayed and then slept and you had been in prayer as long as you were waiting for it.” Al-Hasan said, “The people are regarded as performing good deeds as long as they are waiting for doing good deeds.” Al-Hasan’s statement is a portion of Anas’s Hadith from the Prophet.
As long as you’re waiting to perform a good deed, it is as though you’re performing it. In other words, you’re rewarded for the whole waiting period. (y)
Narrated ‘Abdullah bin ‘Umar:
The Prophet prayed one of the’lsha’ prayer in his last days and after finishing it with Taslim, he stood up and said, “Do you realize (the importance of) this night? Nobody present on the surface of the earth to-night would be living after the completion of one hundred years from this night.”
The people made a mistake in grasping the meaning of this statement of Allah’s Apostle and they indulged in those things which are said about these narrators (i.e. some said that the Day of Resurrection will be established after 100 years etc.) But the Prophet said, “Nobody present on the surface of earth tonight would be living after the completion of 100 years from this night”; he meant “When that century (people of that century) would pass away.”
This was a sign of Prophethood, for what Allah’s Messenger (SAW) said was proved, as the last of his companions to die was Abu at-Tufail Amir bin Wathila who died 100 years after the prophecy of the Prophet (SAW) and he was 110 years old then.
