He also reported Allah's Messenger ﷺ as saying, “The first person to be judged on the day of resurrection will be a man who died as a martyr. He will be brought forward, and after Allah has reminded him of the favour He showed him and the man acknowledges it, He will ask, ‘What did you do to show gratitude for it?’ The man will reply, ‘I fought for Thy cause till I was martyred.’ Allah will say, ‘You lie. You fought that people might call you courageous, and they have done so.’ Command will then be issued about him, and he will be dragged on his face and thrown into hell. Next a man who has acquired and taught knowledge and read the Qur’an will be brought forward, and after Allah has reminded him of the favour He showed him and the man acknowledges it, He will ask, ‘What did you do to show gratitude for it?’ The man will reply, ‘I acquired and taught knowledge and read the Qur’an for Thy sake.’ Allah will say, 'You lie. You acquired knowledge that people might call you learned, and you read the Qur’an that they might call you a reader, and they have done so.’ Command will then be issued about him, and he will be dragged on his face and thrown into hell. Next a man whom Allah has made affluent and whom He has given all kinds of property will be brought forward, and after Allah has reminded him of the favour He showed him and the man acknowledges it, He will ask, ‘What did you do to show gratitude for it?’ The man will reply, ‘I have not neglected to give liberally for Thy sake to all the causes approved by Thee for this purpose.’ Allah will say, ‘You lie. You did it that people might call you generous, and they have done so.’ Command will then be issued about him, and he will be dragged on his face and thrown into hell.” Muslim transmitted it.

Nubaisha al-Hudhali reported Allah's Messenger ﷺ as saying, “The days of at-tashriq* are days of eating, drinking, and remembrance of Allah.” *The three days after the sacrifice on the tenth of Dhul Hijja. The name is said to have been given because the flesh of the victims is cut into strips and put in the sun to dry; but other explanations are also given. Muslim transmitted it.

‘Abdallah b. ‘Amr b. al-‘As told of Allah's Messenger ﷺ saying to him, “Have I not been informed, ‘Abdallah, that you fast during the day and get up at night for prayer?” [Mirqat explains this as meaning all night.] When he replied that that was so, he said, “Do not do it. Fast and break your fast, get up for prayer and sleep, for you have a duty to your body, your eye, your wife, and your visitors. May he who observe a perpetual fast never fast!* Fasting three days every month is equivalent to a perpetual fast. Fast three days every month and recite the Qur'an every month.” When he replied that he was able to do more than that, he said, “Observe the most excellent fast, that of David, fasting every second day, and recite the Qur’an once every seven nights, but do no more than that.” * Cf. the similar phrase in the tradition of Abu Qatada (p.434). Some hold that the meaning here is, ‘He who observes a perpetual fast has not fasted.’ (Bukhari and Muslim.)
