عن عبد الله بن مسعود رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : «إنَّ لله ملائكةً سَيَّاحين في الأرضِ يُبَلِّغوني مِن أُمَّتِي السَّلامَ».
‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "Allah has angels traveling around on earth conveying to me the greetings of my Ummah.”
In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) tells that Allah, the Almighty, has angels who often tour the earth and inform the Prophet (may Allah's peace and blessings be upon him) when any one of this Ummah greets him, saying: Verily, so-and-so sent greetings to you.
