The angel of death seeks His permission to cross the threshold of His door
There is a similar narration in Ma’arij Un Nubuwwah:
Hadhrat ‘Idhrail (May peace be upon him) came on earth with a delegation of 1000 angels who were wearing raiment of rubies and emeralds. They went to the Holy Prophet (Sallallahu alaihi wa sallam), took His permission, entered His house, greeted Him with Salaam and said: Almighty Allah greets you with Salaam and has ordered me that unless and until you permit me, I should not draw out your sacred soul. Hadhrat Jibreel (May peace be upon him) said: O Prophet of Allah (Sallallahu alaihi wa sallam)! I have brought glad tidings. He was asked: What is it? Today all the doors of hell have been closed. Paradise has been beautified. The damsels of paradise have beautified themselves. Angels are standing in rows upon rows waiting for you. The Holy Prophet (Sallallahu alaihi wa sallam) said: These are all glad tidings, but tell me something that will make me even more happy. Jibreel (May peace be upon him) said: Paradise is forbidden on all Prophets and their nations until and unless you and your Ummah enter it. The Holy Prophet (Sallallahu alaihi wa sallam) said: Increase my happiness further! Jibreel (May peace be upon him) said: Almighty Allah has granted you such distinctions that have not been given to any other Prophet, the Houz-e-Kauthar, the Great Intercession, on the Day of Judgment, Allah will pardon so many people from your Ummah that you will be pleased with it. The Holy Prophet (Sallallahu alaihi wa sallam) said: Now my heart is joyful and my eyes have cooled. Thus delighted, the Holy Prophet (Sallallahu alaihi wa sallam) told the angel of death: Fulfill the order given to you. (Ma’arij Un Nubuwwah, Vol. 3, Pg. No. 501)
On 12th Rab’ee Ul Awwal, Wednesday, at the time of Salaat Ul Chaasht, the blessed head of the Holy Prophet (Sallallahu alaihi wa sallam) was in the lap of Hadhrat ‘Aisha (May Allah be well pleased with her). The Holy Prophet (Sallallahu alaihi wa sallam) decided to use Miswak, but it was hard. Hadhrat ‘Aisha (May Allah be well pleased with her) softened the Miswak by chewing on it. Then the Holy Prophet (Sallallahu alaihi wa sallam) used it. A vessel full of water was placed before the Holy Prophet (Sallallahu alaihi wa sallam) and He would dip both His hands in water and wipe over His face saying “La Ilaha Illallah.” Then the Holy Prophet (Sallallahu alaihi wa sallam) raised His hand and said: Allahumma Rafeeqil A’ala. His sacred soul was drawn and His hand fell back. (Sahih Bukhari, Vol. 2, Pg. No. 640, Hadith No. 4184)
