Because Prophet Zakariyyah and his wife had aged and, hence, lost the physical means of bearing children, in this Ayat, Zakariyyah asks Allah for a child and uses the words from Yourself. In other words, this will be a gift that is not the product of any material means, for all such means no longer exist. Hence, this gift can only be a blessing that Allah bestows out of nothing more than His will and graciousness and without conventional, physical human requirements. The word ‘Samee’ means All-Hearing and is an attribute of Allah, but in this context, it refers to Allah’s capacity to answer prayers or supplications. -Zahrat-al-Tafseer and others.
