Question

Is the following Hadith authentic?

“Whomsoever recites ‘La ilaha illalahul malikul haqqul mubin’ one hundred times daily, this will be a means of protection against poverty, he will be safe from the loneliness of the grave, and by virtue of this dhikr, he will knock on the door of Jannah”

Answer

Hafiz Khatib Al Baghdadi (rahimahullah) has recorded this narration, with a weak chain that supposedly goes through Imam Malik (rahimahullah).

(Tarikh Baghdad, vol. 14 pg. 322)

There are a few narrators who have reported this Hadith through Imam Malik (rahimahullah). However Imam Daraqutni and Hafiz Ibn ‘Abdil Barr (rahimahumallah) have stated that no reliable narrator has reported this Hadith from Imam Malik and the attribution to Imam Malik is not sound (la yasihhu ‘anhu). Imam Daraqutni further states that this Hadith is not authentic (la yasihhu).

(Refer: At Tamhid, vol. 6 pg. 156, Al ‘Ilalul Mutanahiyah, vol. 2 pg. 837, Al Ajwibatul Mardiyyah, vol. 1 pg. 337, Lisanul Mizan, vol. 6 pg. 347 -6062-)

However, a person may recite this du’a/dhikr as many times as he wishes without stipulating a number as Hafiz Ibn ‘Abdil Barr (rahimahullah) has stated this indeed is a good du’a, the blessings of it is anticipated.

(At Tamhid, vol. 6 pg. 156)

And Allah Ta’ala Knows best.
