10. Abu Ahmad al-Qasim ibn Muhammad ibn Ahmad al-Sarraj al-Hamdani said: Abu al-Qasim Ja`far ibn Muhammad ibn Ibrahim al-Sarandibi said: Abu al-Hasan Muhammad ibn `Abd Allah ibn Haruna al-Rashid said in Halab that Muhammad ibn Adam ibn Abu Iyas said: Ibn Abu Dhi’b said, on the authority of Nafi`, on the authority of Ibn `Umar that The Messenger of Allah said: Do not hit your children because of their crying. Verily, during the first four months, their cry is bearing witness that there is no god but Allah. During the next four months, when they cry they are sending their blessings upon the Prophet and His Progeny . And during the next four months, they are praying for their parents.
