The Prescribed Dhikr for the Day and the Night

Question:
May Allah reward you with good, and may He do you good. The questioner asks and says: If a person is content with a specific daily dhikr, such as sending blessings upon the Prophet (peace and blessings be upon him) one hundred times a day, is that permissible? Or do you direct him to something else? May Allah reward you with good.

Answer:
For specific dhikr in the morning and evening, one should refer to the authentic references from the books of hadith and books of dhikr, such as the book of Dhikr by Imam al-Nawawi, and the book of al-Ghab by al-Sayyab, and the book of al-Kalim al-Tayyib by Imam Ibn al-Qayyim, and the book of al-Kalim al-Tayyib by Shaykh al-Islam Ibn Taymiyyah. One takes from these books the dhikr that is said in the morning and evening, and the dhikr that is said at specific times prescribed by the Shari'ah, and in specific states; all of this is detailed in these books.
As for sending blessings upon the Prophet (peace and blessings be upon him), it is prescribed and has great virtue, but specifying it as one hundred times, or less, or more, requires evidence. A person sends blessings upon the Prophet (peace and blessings be upon him) and increases in sending blessings upon him without specifying a number. He (peace and blessings be upon him) said: This is a great good. Yes.
