"Indeed, a woman from the wives of the people of Paradise, the whiteness of her shin is visible through seventy garments until her marrow is seen, and that is because Allah, he Exalted, says: As if they are corundum and Marjan. So, as for the corundum, it is a stone that if you were to enter a wire through it, then you polished its cloudiness away, you would surely be able to see it through it." Another chain reports a similar narration.
Jami` at-Tirmidhi Book 38, Hadith 11
The Prophet (ﷺ) said, "You should not say, 'Feed your lord (Rabbaka), help your lord in performing
ablution, or give water to your lord, but should say, 'my master (e.g. Feed your master instead of lord
etc.) (Saiyidi), or my guardian (Maulai), and one should not say, my slave (Abdi), or my girl-slave
(Amati), but should say, my lad (Fatai), my lass (Fatati), and 'my boy (Ghulami).
Sahih al-Bukhari Book 49, Hadith 35
Abu Bakr (Allah be pleased with him) came and sought permission to see Allah's Messenger (ﷺ). He found people sitting at his door and none amongst them had been granted permission, but it was granted to Abu Bakr and he went in. Then came 'Umar and he sought permission and it was granted to him, and he found Allah's Apostle (ﷺ) sitting sad and silent with his wives around him. He (Hadrat 'Umar) said: I would say something which would make the Prophet (ﷺ) laugh, so he said: Messenger of Allah, I wish you had seen (the treatment meted out to) the daughter ofKhadija when you asked me some money, and I got up and slapped her on her neck. Allah's Messenger (mav peace be upon him) laughed and said: They are around me as you see, asking for extra money. Abu Bakr (Allah be pleased with him) then got up went to 'A'isha (Allah be pleased with her) and slapped her on the neck, and 'Umar stood up before Hafsa and slapped her saying: You ask Allah's Messenger (ﷺ) which he does not possess. They said: By Allah, we do not ask Allah's Messenger (ﷺ) for anything he does not possess. Then he withdrew from them for a month or for twenty-nine days. Then this verse was revealed to him:" Prophet: Say to thy wives... for a mighty reward" (xxxiii. 28). He then went first to 'A'isha (Allah be pleased with her) and said: I want to propound something to you, 'A'isha, but wish no hasty reply before you consult your parents. She said: Messenger of Allah, what is that? He (the Holy Prophet) recited to her the verse, whereupon she said: Is it about you that I should consult my parents, Messenger of Allah? Nay, I choose Allah, His Messenger, and the Last Abode; but I ask you not to tell any of your wives what I have said He replied: Not one of them will ask me without my informing her. God did not send me to be harsh, or cause harm, but He has sent me to teach and make things easy.
Sahih Muslim Book 18, Hadith 39
"Indeed the best of my friends to me is the one of meager conditions, whose share is in Salat, worshipping his Lord well and obeying him (even) in private. He is obscure among the people such that the fingers are not pointed towards him. His provisions are only what is sufficient and he is patient with that." Then he tapped with his fingers and said: "His death comes quickly, his mourners are few, and his inheritance is little."With this (the above), chain it is narrated that the Prophet (s.a.w) said: "My Lord presented to me, that He would make the valley of Makkah into gold for me, I said: 'No O Lord! But being filled for a day and hungry for a day"-or he said: "three days" or something like that- "So when I am hungry, I would beseech You and remember You, and when I am full I would be grateful to You and praise You."
