There are marfoo‘ hadeeths about the virtue of reading Soorat al-Dukhaan, but none of them are saheeh.
With regard to the first hadeeth:
It was narrated from Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (blessings and peace of Allah be upon him) said:
“Whoever recites Ha-Meem (soorat) al-Dukhaan on the night before Friday will be forgiven.”
It was narrated by al-Tirmidhi (2889) via Hishaam Abu’l-Miqdaam, from al-Hasan, from Abu Hurayrah.
Then al-Tirmidhi said: We only know this hadeeth through this isnaad, and Hishaam Abu’l-Miqdaam is da‘eef. And al-Hasan did not hear from Abu Hurayrah. This was the view of Ayyoob, Yoonus ibn ‘Ubayd and ‘Ali ibn Zayd.
Thus the hadeeth has two faults:
1. Abu’l-Miqdaam Hishaam ibn Ziyaad: the muhadditheen are unanimously agreed that he is to be regarded as da‘eef. Ibn Hibbaan said: He narrates fabricated reports from trustworthy narrators, and it is not permissible to quote him as evidence. See: Tahdheeb al-Tahdheeb, 11/39.
2. There is a break in the isnaad between al-Hasan and Abu Hurayrah.
Hence it was classed as da‘eef by Ibn al-Jawzi in al-Mawdoo‘aat (1/247), Ibn al-‘Arabi in ‘Aaridah al-Ahwadhi, 6/35, and al-Albaani in Da‘eef al-Tirmidhi.
The second hadeeth:
In his Tafseer (4/46), al-Waahidi narrated a hadeeth from Ubayy ibn Ka‘b that is similar to the hadeeth quoted above, except that its isnaad includes Sallaam ibn Saleem who is accused of lying. Hence Shaykh al-Albaani, in al-Silsilah al-Da‘eefah (no. 4632), ruled that it is da‘eef jiddan (very weak).
Ahmad ibn Manee‘ also narrated it from Ubayy ibn Ka‘b in his Musnad, as it says in al-Busayri’s Ithaaf al-Khiyarah al-Maharah (6/89). Then he said: This isnaad is weak because Haroon ibn Katheer is not known.
The third hadeeth:
It was narrated from Abu Umaamah (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said:
“Whoever recites Ha-Meem al-Dukhaan on the night before Friday or on Friday, Allah will build for him a house in Paradise.”
This was narrated by al-Tabaraani in al-Mu‘jam al-Kabeer (8/264).
Shaykh al-Albaani (may Allah have mercy on him) said:
(It is) da‘eef jiddan. It was narrated by al-Asfahaani in al-Targheeb wa’l-Tarheeb (p. 244) from Hafs ibn ‘Umar al-Maazini: Fidaal ibn Jubayr told us, from Abu Umaamah in a marfoo‘ report…
I [Shaykh al-Albaani (may Allah have mercy on him)] say: This isnaad is da‘eef jiddan. With regard to Fidaal ibn Jubayr, Ibn Hibbaan said: It is not permissible to quote him as evidence under any circumstances; he narrated hadeeths that have no basis. Because of him, al-Haythami regarded it as a faulty hadeeth and said (2/168): It was narrated by al-Tabaraani in al-Kabeer and its isnaad includes Fidaal ibn Jubayr, who is da‘eef jiddan, and Hafs ibn ‘Umar al-Maazini, who is not known, as it says in al-Lisaan. End quote.
Silsilah al-Ahaadeeth al-Da‘eefah wa’l-Mawdoo‘ah, 11/191, no. 5112
This hadeeth is also classed as da‘eef in Fataawa al-Lajnah al-Daa’imah, 3/141
And Allah knows best.
