Surah An-Nahl was revealed during the last Makkah period of the Prophet Muhammad's prophethood and emphasizes the concepts of monotheism (Tawhid) while refuting polytheism (Shirk). The Surah addresses the consequences of disbelief, encourages moral conduct aligned with faith, and comforts believers facing persecution. It also highlights numerous signs of Allah's creation as evidence of His existence and power, urging reflection and gratitude among the people.
