Like other Muslim communities with roots in Iran and Central Asia, the Ismailis observe the festival of Navroz in the spirit of humble thanksgiving to Allah for His bountiful creation and blessings. In Sura Ya-Sin of the Holy Qur’an, Allah says:
Let the once dead earth be a sign to them. We gave it life, and from it produced grain for their sustenance. We planted it with palm and the vine and watered it with gushing springs, so that men might feed on its fruit. It was not their hands that made all this. Should they not give thanks?
— Surah 36, Verses 33–35
