The Virtue of the Night Prayer, Feeding the Hungry, and Frequent Fasting

Abu Bakr ibn Abi Dawud said: Ibn al-Mundhir al-Turayfi narrated to us, Ibn Fudayl narrated to us, 'Abd al-Rahman ibn Ishaq narrated to us, from al-Nu'man ibn Sa'd, from 'Ali ibn Abi Talib (may Allah be pleased with him), who said: The Messenger of Allah (ﷺ) said:

"Indeed, in Paradise there are chambers whose outsides can be seen from their insides, and whose insides can be seen from their outsides." It was said to the Messenger of Allah: "For whom are they?" He replied: "For the one who speaks pleasantly, feeds others, fasts continuously, and prays at night while people are asleep."

Al-Tirmidhi also narrated it from 'Ali ibn Hujr, from 'Ali ibn Mushir, from 'Abd al-Rahman ibn Ishaq, and said: It is gharib (unfamiliar); we do not know it except from his hadith.

Al-Tabarani narrated from the hadith of al-Walid ibn Muslim: Mu'awiyah ibn Sallam narrated to us, from Yazid ibn Sallam, Abu Sallam narrated to me, Abu Musa al-Ash'ari narrated to me, Abu Malik al-Ash'ari narrated to me that the Messenger of Allah (ﷺ) said:

"Indeed, in Paradise there are chambers whose exteriors can be seen from their interiors, and whose interiors can be seen from their exteriors, which Allah has prepared for the one who feeds others, fasts continuously, and prays at night while people are asleep."

Al-Tabarani also narrated from the hadith of Ibn Wahb: Hayyay narrated to me, from 'Abd al-Rahman, from 'Abdullah ibn 'Amr, from the Prophet (ﷺ), who said:

"Indeed, in Paradise there are chambers whose exteriors can be seen from their interiors, and whose interiors can be seen from their exteriors."

Abu Malik al-Ash'ari said: "For whom are they, O Messenger of Allah?" He replied:

"For the one who speaks pleasant words, feeds others, and spends the night standing in prayer while people are asleep."

Al-Hafiz al-Diya' said: "In my view, this is a hasan (good) chain of transmission, and the mention of Abu Malik in it is an indication of its soundness, as he narrated it, as well as the chain of his hadith."

It has also been mentioned in some hadiths that a palace may consist of a single pearl, including its doors, door leaves, and ceiling.

And in another hadith:

"The ceilings of Paradise are light, shimmering like flashing lightning; were it not that Allah stabilizes their sight, it would almost snatch it away."
