What is prescribed at the beginning of the first night of Ramadan

Question:
Is there a report that the Salaf (the earliest generations) used to celebrate when Ramadan entered, and what is prescribed when the first night of this blessed month enters?

Answer:
What is prescribed is supplication: “O Allah, bring it to us with safety and faith, well-being and Islam. My Lord and your Lord is Allah. A crescent of good and guidance.” One should also make du'a' (supplication). This is what is called al-istihlal (seeking the new moon). The Prophet (peace and blessings be upon him) used to make du'a' upon seeing the crescent. It is also prescribed to welcome Ramadan with joy, happiness, and gladness, to perform tarawih (the Ramadan night prayer) in the nights of Ramadan, to increase in reciting the Qur'an, to increase in repentance and seeking forgiveness, and to occupy one's time with obedience to Allah. This is what is prescribed in Ramadan from the first night to the last night.
