[3195] Iṣdaʿ is a command, a very robust one, to the Noble Messenger (ﷺ) to declare his call openly in full view of people. The root ṣ-d-ʿ denotes a crack and an opening in something (cf. cf. al-Ṭabarī, Ibn Qutaybah, Gharīb al-Qur’ān, Ibn Fāris, Maqāyīs al-Lughah); that is to break apart Truth from falsehood so that everyone is in no doubt about where they stand (cf. Ibn Kathīr, al-Shawkānī, Ibn ʿĀshūr).
[3196] The Messenger (ﷺ) is to carry out this command in spite of all the opposition and derision of the Associators that he was up against (cf. al-Ṭabarī, Ibn Kathīr, al-Saʿdī).
