Hazrat ibn Umar (Radhiyallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) prohibited qaza’. Qaza’ refers to where a part of the head of a child is shaved and a part is left unshaved.
عن ابن عمر أن النبى صلى الله عليه وسلم رأى صبيا قد حلق بعض شعره وترك بعضه فنهاهم عن ذلك وقال:احلقوه كله أو اتركوه كله (ابو داود رقم 4197)
Hazrat ibn Umar (Radhiyallahu Anhu) reports that on one occasion Rasulullah (Sallallahu Alaihi Wasallam) saw a child who a part of his head was shaved and a part was left unshaved. Rasulullah (Sallallahu Alaihi Wasallam) prohibited them (the family) from doing this and said: “Either shave all of it (the hair) or leave all of it (as normal while all are even length).”
