Pronouncing Intentions

Some scholars believed that it is recommended to pronounce the intention verbally.

Ibn Kathir narrates that Al-Hamdani said:

كان أبي إذا أراد أن يؤدبني أخذ العصا بيده ثم يقول : نويت أن أضرب ولدي تأديبا كما أمر الله ثم يضربني ، قال : وإلى أن ينوي ويتمم النية كنت أهرب

“Whenever my father intended to discipline me, he used to grab his walking-stick and say: “I hereby intend to discipline my son, … etc, etc.”
Al-Hamdani said: I used to escape before he could finish his intentions!!”

[“Al-Bidayah wa-Nihayah”, 12/188].
