Is this hadith authentic Abdullah ibn amr said there is palace in jannah called as adn in which there are 5000 doors in each door there will be 5000 hoors only nabi siddique or shaheed will enter through it (musannaf ibn shybah)?Who ever reads surah dakan friday allah will wed him to hoor on that day (sunan darmi)?How many hoors for lowest jannati as hafith iraqi mubarkfuri and mulla ali qari said that it becomes clears he will get 70 hoors and 2 womens of this world ?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

The first hadeeth, “Indeed, in Paradise there is palace called "Eden"...” was reported by Ibn Abi Shaybah in Al-Musannaf as a Mawqoof hadeeth (attributed to the Companion 'Abdullah ibn 'Amr ibn Al-'Aas) and not as a Marfoo' hadeeth (attributed to the Prophet, sallallaahu`alayhi wa sallam), but it takes the ruling of the Marfoo' one, because it is not of what can be based on one's own opinion.

We did not find any sayings of the scholars regarding its chain of transmission, whether it is sound or weak. However, its men are Thiqaat (trustworthy). He reported it from Ghundar from Shu'bah from Ya'laa ibn 'Ataa', who said: I heard Ya'qoub ibn 'Aasim ibn 'Urwah ibn Mas'oud narrating from 'Abdullah ibn 'Amr, who said, “In Jannah, there is palace called Eden wherein are five thousand doors, in each door there are five thousand hoors; he said: I think Ya'laa said: Only a prophet, a Siddeeq (one who has reached the highest level of faith) or a martyr will enter through it.” There is no one who found fault with its transmitters.

The other hadeeth, “Whoever recites Ad-Dukhan during Friday night shall be forgiven, and will be married to hoors,” was reported by Ad-Darimi as a Mawqoof hadeeth (attributed to a Companion) but it takes the ruling of the Marfoo' one, because such one is not said based on one's own opinion. Dr. Al Zahraani said in his revision of Musnad Ad-Darimi: Its men are Thiqaat (trustworthy). And that is true, as it is reported from Muhammad ibn Al-Mubarak that Sadaqah ibn Khalid narrated to us from Yahyaa ibn Al-Harith from Abi Rafi', who said, “Whoever recites Ad-Dukhan during Friday night shall be forgiven and will be married to hoors.”

Finally, we apologize for not answering your other question, as we indicated in the question entry section that only one question is allowed at a time. It is only one question that is answered when more than one question is asked.

Allah knows best.
