Just as we do tawaf around the holy Ka'ba on earth, the Angels make a tawaf around Baitul Mamura.
Baitul Ma'mur, also known as the "Frequent House", is the prototype of the Ka'ba, the House of Allah (SWT), and it is outside the human kingdom. It is located directly above the Kaaba in the highest Heaven, ie, the Seventh Heaven and above it is the throne of Allah (SWT). This sacred and holy house is also mentioned in the Surah Tour of the Holy Quran, where almighty Allah says;
"And Byte-ul-Mamur (house over the heavenly parable to the Kaaba in Mecca, constantly visited by angels)" (Holy Koran-Sura 52: 4)
Just as we are performing the tawaf around the Holy Kaaba on earth, the Angels are making a tawaf around Baitula Mamur day in and day out. 70,000 angels performing tawaf in Baitul Ma'mur just to worship and pray every day that never return, so Baitul Ma'mur is welcomed by a new legion of 70,000 angels every day, which puts in perspective a huge amount of angelic population that exists in comparison to mortal people living on earth. The Messenger of Allaah (peace be on him) said in the hadith about Isra and Mirage (Night Journey and ascension to Heaven):
"Then they showed me Al-Bait-al-Mamur (ie, the House of Allah). I asked Gabriel about this and he said: "This is Al-Bait-ul-Mamur, where 70,000 angels visit every day and when they leave, never return to it (but always includes a fresh daily party)" (Sahih Bukhari 3207 and Saheeh Muslim 164)
In the same hadith it is narrated that the Prophet (peace and blessings of Allaah be upon him) said:
"Then Bait-ul-Ma'mur was raised to me. I said: Oh, Gabriel! what is it? He replied: This is Byt-ul-Mamur. Seventy thousand angels enter it daily, and after they go out, they no longer return. Then I was delivered two vessels. The first was wine, and the second - milk, and they were both in front of me. I chose milk. It was said: you did the right thing. Allah will guide you through your Ummah at a natural rate. Then fifty prayers daily were obligatory for me. And then he passed the rest of the hadith to the end "(Saheeh al-Bukhari 3207, Saheeh Muslim 164)
Angels come to offer their lard, and as soon as they end, they leave to never return. Then they are followed by another group of 70,000 angels who pray and go; This cycle will continue until the Day or Resurrection. It is also believed that every day the leader of the group of angels is assigned the duty to take the other angels to a specified place located in Heaven, where they will stand and participate in the zikre until the end of time and on the Day of Judgment.
This serves as a reminder to all of us that Allah (SWT) does not need our worship. In fact, this is the complete opposite. We need to worship Allah (SWT) and participate in ibadah so that we can be saved from the burning fire of Hell. We are the ones who need to kneel and bow our heads to the Almighty Allah, so that He can guide us, protect us and forgive all our sin, so we can have the chance to enter Jannah (paradise). The number of angels is great, and their only goal is to worship Allah (SWT) all day, every day. Therefore, Allah (SWT) does not need our prayers. He has endless legions of Angels worshiping Him. We are the ones who need Allah (SWT) and His mercy, because without Allah (SWT) we cannot achieve any semblance of peace, happiness or success in this world or in the Hereafter.
