´Al-'Abbas narrated from Abu Sallam Al-Habashi who said:` "'Umar bin 'Abdul-'Aziz summoned me so I got a ride on a mule." [He said:] "When he entered upon him, he said: 'O Commander of the Believers! My riding mule was troublesome for me.' So he said: 'O Abu Sallam!I did not want to trouble you, but a Hadith which you narrated-from Thawban, from the Prophet (s.a.w) about the Hawd-was conveyed to me,and I wanted you to narrate it directly to me."'Abu Sallam said: "Thawban narrated to me from The Messenger of Allah (s.a.w) who said 'My Hawd (is as large as) from 'Adan to 'Amman of Al-Balqa', its water is whiter than milk and sweeter than honey. Its cups are as numerous as the stars, whoever drinks one drink from it, he will never be thirsty after that again. The first people to arrive at it are the poor among the Muhajirin with disheveled heads, dirty clothes, those whom the women of favor would not marry, nor would the doors be open for them.' 'Umar said: 'But I have married a women of favor and the doors are open for me. I married Fatimah bint 'Abdul-Malik. I shall certainly not wash my head until it is disheveled, nor wash my garment which touches my body until it becomes dirty." Another chain reports a similar narration.

´It was narrated that Abu Sallam Al-Habashi said:` “Umar bin ‘Abdul-‘Aziz sent for me and I came to him upon the riding animal prepared for swift mail delivery. When I came to him, he said: ‘We have caused you some trouble O Abu Sallam.’ He said: ‘Yes, by Allah, O Commander of the Believers!’ He said: ‘By Allah, we did not want to cause you any hardship, but there is a Hadith which I have heard that you narrate from Thawban, the freed slave of the Messenger of Allah (ﷺ), concerning the Cistern, and I wanted to hear it directly from you.’ He said: “I said: ‘Thawban, the freed slave of the Messenger of Allah (ﷺ), told me that the Messenger of Allah (ﷺ) said: “My Cistern is (wider than) the distance between Ailah and ‘Aden. It is whiter than milk and sweeter than honey, and its cups are as many as the stars in the sky. Whoever drinks from it will never feel thirst again. The first ones who come to drink from it will be the poor Muhajirin, with dirty clothes and disheveled hair, who do not marry refined women and for whom no doors are opened.” ‘Umar wept until his beard became wet, then he said: ‘But I have married refined women and doors have been opened for me. Certainly I will not wash the clothes that are on my body until they become dirt, and I will not comb my hair until it becomes disheveled.’”

Benefits and Issues: (1) If a poor and unknown Muslim is righteous, then he has a great status in the sight of Allah.
(2) If Allah Almighty grants wealth, then adopting simplicity instead of adornment and pride becomes a means of elevation in ranks.
(3) The meaning of "doors being opened" is that, due to his high status in the world, everyone respects him, and wherever he goes, people open their doors to welcome him. Whereas the poor man is treated in the opposite manner.
(4) Having disheveled and untidy hair does not mean that one should neglect proper cleanliness and hygiene. Rather, it means that one should not be excessively absorbed in adornment and beautification.
(5) Despite being a caliph, Umar ibn Abd al-Aziz (rahimahullah) was so fond of the knowledge of hadith that whenever he learned that a scholar had memorized a hadith, he did not consider it beneath him to benefit from him. Muslim rulers should be like this.
(6) It is the duty of the scholars ('ulama) to respect rulers who love the religion, and to make every effort to comply with their commands.
(7) Umar ibn Abd al-Aziz (rahimahullah) did not send the order that they should come immediately, but Abu Salam (rahimahullah) endured hardship in obedience to the leader and tried to reach as soon as possible.
