It's generally accepted that there are around 750 verses in the Quran dealing with natural phenomenon. In many of these verses the study of nature is "encouraged and highly recommended," and historical Islamic scientists like Al-Biruni and Al-Battani derived their inspiration from verses of the Quran. Mohammad Hashim Kamali has the stated that "scientific observation, experimental knowledge and rationality" are the primary tools with which humanity can achieve the goals laid out for it in the Quran. Ziauddin Sardar built a case for Muslims having developed the foundations of modern science, by highlighting the repeated calls of the Quran to observe and reflect upon natural phenomenon. "The 'scientific method,' as it is understood today, was first developed by Muslim scientists" like Ibn al-Haytham and Al-Biruni, along with numerous other Muslim scientists.
