THIRD REMINDER. Yaumul Ithnayn, 10th day of Jumaadal Aakhir (Monday, 26th February). Let's continue with the history of the Prophet Muhammad sallallaahu alaihi wasallam. Bismillaahir Rahmaanir Raheem. With regard to the point on which there is scholarly disagreement, that has to do with defining the month and the day of the month. We have come across many opinions concerning that, including the following:  That he was born on 2nd day Rabeeul-Awwal. Ibn Katheer (may Allah have mercy on him) said:  It was said that he was born on the second of the month. As-Seerah an-Nabawiyyah, 1/199  It was said that he was born on 8th Rabee‘ al-Awwal. Ibn Katheer (may Allah have mercy on him) said: It was said that he was born on the eighth of the month. As-Seerah an-Nabawiyyah, 1/199  It was said that he was born on 10th Rabee ‘ al-Awwal. Ibn Katheer (may Allah have mercy on him) said: It was said that he was born on the tenth of the month. As-Seerah an-Nabawiyyah, 1/199  It was said that he was born on 12th Rabee ‘ al-Awwal. Ibn Katheer (may Allah have mercy on him) said: It was said that he was born on the twelfth of the month. This was stated by Ibn Ishaaq. It was narrated by Ibn Abi Shaybah in his Musannaf from ‘Affaan from Sa‘eed ibn Meena’ that Jaabir and Ibn ‘Abbaas said: The Messenger of Allah (blessings and peace of Allah be upon him) was born in the Year of the Elephant on Monday 12th Rabee‘ al-Awwal; on Monday his mission began, on Monday he was taken up to heaven, on Monday he migrated, and on Monday he died. This is the well-known opinion according to the majority. And Allah knows best. As-Seerah an-Nabawiyyah, 1/199  What appears to us to be the case is that the strongest opinion concerning the birth of the Prophet (blessings and peace of Allah be upon him) is that he was born between the eighth and the twelfth of Rabee‘ al-Awwal. Some Muslim mathematicians and astronomers have determined that the Monday in question was the ninth of Rabee‘ al-Awwal. It may be that this is another opinion, and it has some merit. That corresponds to 20th April 571 CE. This is what the authors of some modern books on Seerah (Prophet’s biography) regard as most likely to be correct, including Professor Muhammad al-Khudari and Safi ar-Rahmaan al-Mubaarakfoori.  Abu’l-Qaasim as-Suhayli (may Allah have mercy on him) said:  The mathematicians say that his birth occurred in the solar month of April, on the twentieth of that month. Ar-Rawd al-Unuf, 1/282  Prof. Muhammad al-Khudari (may Allah have mercy on him) said:  The Egyptian astronomer Mahmoud Basha (d. 1885 CE) who was well-versed in astronomy, geography and mathematics, and wrote several books based on his research stated that it was on the morning of Monday 9th Rabee‘ al-Awwal, which corresponds to 20th April 571 CE. That corresponds to the first year following the elephant incident. He was born in the house of Abu Taalib in Shi‘ab Banu Haashim.  Noor al-Yaqeen fi Seerat Sayyid al-Mursaleen (p. 9). See also ar-Raheeq al-Makhtoom (p. 41).  In summary, what should be important to us is to follow what is important as the prophet taught, that's to fast each Monday to avoid causing divisions in the religion through any other activities. May ALLAH keep guiding us all from any deviation. Aameen.
