The Companions (may Allah be pleased with them) used to comply with the Prophet’s ﷺcommands and adhere to the Islamic etiquettes, and they (may Allah be pleased with them) left the most wonderful legacy attesting that. In this hadeeth, the Tabi’ee (Follower) ‘Ubayd ibn ‘Umayr stated that Aboo Moosaa, ‘Abdullah ibn Qays Al-Ash’aree (may Allah be pleased with him) sought permission thrice to enter ‘Umar’s house, as recorded in Saheeh Al-Bukhaaree and Saheeh Muslim. However, the Caliph ‘Umar (may Allah be pleased with him) was busy and did not give him permission to enter, and therefore he left. When ‘Umar (may Allah be pleased with him) finished his task, he ordered that Aboo Moosaa (may Allah be pleased with him) should be given permission to enter, but he was told that he had left. ‘Umar summoned Aboo Moosaa (may Allah be pleased with them) and inquired about his reason for leaving instead of waiting to be given permission to enter. Aboo Moosaa told him that he was acting upon the command of the Prophet ﷺ in this regard. It has been narrated in Saheeh Al-Bukhaaree and Saheeh Muslim that the Prophet ﷺ said: “When one of you seeks permission thrice to enter and it is not granted to him, he should go back.” Upon hearing the hadeeth, ‘Umar (may Allah be pleased with him) was shocked that such etiquette should have missed him, while he (may Allah be pleased with him) accompanied the Prophet ﷺ in residence and travel! He (may Allah be pleased with him) feared that Aboo Moosaa (may Allah be pleased with him) might have been confused and therefore asked him to bring a witness to testify to the authenticity of this act of Sunnah so that people would not take lightly the attribution of a statement or an act to the Prophet ﷺ. Aboo Moosaa (may Allah be pleased with him) went to the Ansaar’s meeting place and asked them to testify with him that this hadeeth was authentically attributed to the Prophet ﷺ. Since this matter was well-known and quite common among the Ansaar, they sent with Aboo Moosaa a young Companion Aboo Sa’eed Al-Khudree to ‘Umar (may Allah be pleased with them), and he testified as to the authenticity of the relevant hadeeth. Upon knowing that and learning of the authentic hadeeth on that act of Sunnah, ‘Umar (may Allah be pleased with him) attributed the reason for his lack of knowledge of it to his preoccupation with trade and spending a lot of time in the marketplaces. The Arabic word ‘Safq’ used in the hadeeth means handshakes upon concluding sales transactions. It is deduced from the hadeeth that Muslims are required to investigate the authenticity of any statement before attributing it to the Prophet ﷺ. It is also inferred that when a Companion (may Allah be pleased with him) said: “We were commanded”, it meant that the Prophet ﷺ commanded them. The hadeeth also highlights that senior Companions (may Allah be pleased with them) engaged in trade and worked to earn their living. It is also deduced from the hadeeth that the Companions (may Allah be pleased with them) complied with the Prophet’s command and accepted it upon verifying its authenticity. It is also inferred therefrom that even a knowledgeable scholar (like ‘Umar) may be ignorant of some knowledge issues that may be known to someone else who is less knowledgeable! .
