Abdu'llah bin 'Amr bin 'As (RA) reported: It was conveyed to the Apostle of Allah (ﷺ) that I observe fast successively and pray during the whole night. He sent for me or I met him and he (the Holy Prophet) said: It has been conveyed to me that you observe fast continuously and do not break it and pray during the whole night. Don't do that. for there is share for your eyes, share for your own self, share for your family; so observe fast and break it, pray and sleep and observe fast for one day during the ten days, and there is a reward for you (for other) nine (days besides the tenth day of the fast). I said: Apostle of Allah (ﷺ) , I find myself more powerful than this. He said: Then observe the fast of David (peace be upon him). He ('Amr) said: Apostle of Allah (ﷺ) , how did David observe fast? He (the Holy Prophet) said: He used to fast one day and break it on the other day, and he did not run (from the battlefield) as he encountered (the enemy). He said: Apostle of Allah (ﷺ) , who can guarantee this for me (will I also encounter the enemy dauntlessly)? 'Ata', the narrator of the hadith, said: I do not know how there (crept in) the matter of perpetual fast. The Apostle of Allah (ﷺ) , however, said: He who observed perpetual fast did not fast at all; he who observed perpetual fast did not fast at all, he who observed perpetual fast did not fast at all.

This hadith has been narrated by Ibn Juraij with the same chain of transmitters. Imam Muslim has narrated this hadith on the authority of Abu 'Abbas al-Sa'ib bin Farrukh and he was a trustworthy and reliable (narrator) among the people of Makkah.

'Abdullah bin 'Amr (RA) (Allah be pleased with both of them) reported: The Messenger of Allah (ﷺ) said to me: 'Abdullah bin 'Amr (RA) , you fast continuously and stand in prayer for the whole of night. If you do like that, your eyes would be highly strained and would sink and lose sight. There is no (reward for) fasting (for him) who fasts perpetually. Fasting for three days during the month is like fasting, the whole of the month. I said: I am capable of doing more than this, whereupon he said: Observe the fast of David. He used to fast one day and break (the other) day. And he did not turn back in the encounter.

'Abdullah bin 'Amr (Allah be pleased with both of them) reported: The Messenger of Allah (ﷺ) said to me: I have been informed that you stand for prayer the whole of night and fast during the day. I said: I do that, whereupon he said: If you did that you in fact strained heavily your eyes and made yourself weak. There is a right of your eyes (upon you) and a right of your self (upon you) and a right of your family (upon you). Stand for prayer and sleep. Observe fasts and break (them).

It has been narrated on the authority of Ibn 'Amr who said: The Messenger of Allah (ﷺ) besieged the people of Ta'if, but did get victory over them. He said: God willing, we shall return. His Companions said: Shall we depart without having conquered it? The Messenger of Allah (ﷺ) said: (All right) make a raid in the morning. They did so and were wounded (with the arrows showered upon them). So the Messenger of Allah (ﷺ) said: We shall depart tomorrow. (The narrator says): (Now) this (announcement) pleased them, and the Messenger of Allah (ﷺ) laughed at (their waywardness).

'Abdullah bin 'Amr reported that a person came to Allah's Apostle (ﷺ) and sought permission (to participate) in Jihad, whereupon he (the Holy Prophet) said: Are your parents living? He said: Yes. Thereupon he (the Holy Prophet) said: You should put in your best efforts (in their) service.

This hadith has been narrated on the authority of Habib with the several chains of transmitters.
