Al-Matalib al-'Aliyah 4205 — The birth of the Messenger of Allah ﷺ

It is narrated from Sayyiduna Hassan bin Thabit (may Allah be pleased with him) that he stated: "At that time I was a sensible and alert boy of seven or eight years, who heard well and understood whatever I saw, when suddenly a Jew climbed onto one of the high fortresses of Madinah and began calling out at the top of his voice: 'O Jews!' So they all gathered around him and asked: 'What has happened to you, and what is this matter?' He replied: 'Tonight the star of Ahmad (peace and blessings be upon him) has risen, with which he has been born.'" The narrator (Muhammad bin Ishaq) says: I asked Sa'id bin Abd al-Rahman bin Hassan bin Thabit: "How old was Sayyiduna Hassan bin Thabit (may Allah be pleased with him) when the Messenger of Allah (peace and blessings be upon him) came to Madinah?" He replied: "He was sixty years old."
Imam al-Bayhaqi narrated this hadith in Dala'il al-Nubuwwah. This report is an important historical testimony to the cosmic signs that appeared at the time of the blessed birth of the Messenger of Allah (peace and blessings be upon him), and its narrator Muhammad bin Ishaq is a great imam in the field of the Sirah and the Maghazi.
