Al-Hubab ibn al-Mundhir

Al-Ḥubāb ibn al-Mundhir (raḍiyallāhu ʿanhu) was one of the Anṣār from the Khazraj tribe, known for his expertise in desert travel and reconnaissance. He is immortalized in the Seerah for a crucial strategic intervention at the Battle of Badr (17 Ramaḍān 2 AH). When the Prophet ﷺ had encamped the Muslim army on the outskirts of the Badr plain, al-Ḥubāb approached him and asked a question that distinguished him from all the other Companions at that moment: 'Yā Rasūlallāh, is this campsite one that Allāh has revealed to you, such that we cannot move an inch forward or back? Or is it your own strategic judgment?' When the Prophet ﷺ confirmed it was his own ijtihād, al-Ḥubāb said: 'Then I suggest we advance until we are past the midpoint of the plain, so that the wells of Badr are behind us. We will have unlimited water; they will have to rely on whatever they brought from Makkah.' According to one narration, Jibrīl ʿalayhi s-salām came and confirmed: follow the advice of al-Ḥubāb. The Prophet ﷺ moved the camp accordingly, filled all the smaller side-wells into the main central well, and cut off the Quraysh from any water source. This single tactical decision had an immense demoralizing effect on the Quraysh. Al-Ḥubāb's question, distinguishing between Prophetic waḥy and strategic ijtihād, has become a foundational example in uṣūl al-fiqh discussions about the nature of Prophetic authority.
