We thank you for your question and it is our pleasure to answer them.

The last three Prophets were Yahya – The son of Zakariyya, Isa and Muhammad ( May Allah be pleased with them).

Concerning the birthdate of the Prophet Muhammad (pbuh), Ibn al-Qayyim (may Allah have mercy on him) said: There is no difference of opinion concerning the fact that he (blessings and peace of Allah be upon him) was born in Makkah, and that his birth was in the Year of the Elephant. The Year of the Elephant during that time corresponds to the year 570 CE or 571 CE.

With regard to the day, It was a Monday. He (blessings and peace of Allah be upon him) was born on a Monday, his mission began on a Monday and he died on a Monday. It was narrated that Abu Qataadah al-Ansaari (may Allah have mercy on him) said: The Prophet (blessings and peace of Allah be upon him) was asked about fasting on Mondays and he said: “That is a day on which I was born and on it my mission began – or Revelation came to me.” Concerning the actual date, there is no concensus among the scholars.  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, that corresponds to 20^th April 571 CE.

Concerning the children are as follows,

According to the most correct opinion, he had seven children, three boys and four girls. The boys were:

1-al-Qaasim

2-‘Abd-Allaah

3-Ibraaheem

And the girls were:

1-Zaynab

2-Ruqayyah

3-Umm Kulthoom

4-Faatimah

All of his children died during his lifetime, apart from Faatimah who died after him (peace and blessings of Allaah be upon him).

God willing that answers your questions..
