Is it true that whoever says “(My Lord, leave me not alone, and You are the best of inheritors)” forty times will be granted a child?

Question:
Please, my brother Abu Salim. Peace be upon you. And upon you be peace. Peace be upon you. We want to ask the Shaykh, may Allah preserve you. Raise your voice, Abu Sami, so the Shaykh can hear you. Please go ahead. One of the students of knowledge says that whoever supplicates to Allah in his prostration forty times will be granted a child, and he says this is based on experience. What is the ruling on this statement?

Answer:
The ruling is that it is not permissible to act upon this unless there is evidence specifying the number forty, or fifty, or less, or more; it requires evidence. However, he should supplicate to his Lord to grant him righteous offspring, and if he supplicates with the supplication of Zakariyya and says , that is good. Yes.
