If it is established with an authentic [and reliable] chain of transmission that, as a miracle, the Blessed Messenger (Allah bless him and give him peace) did not have a shadow, no Muslim will hesitate in accepting this fact. However, there are no reports with a reliable chain of transmission on this issue. There is no mention of such a hadith regarding this issue in the well-known hadith compilations such as the Sihah Sittah, etc. However, there is a single narration mentioned by Imam Jalal al-Din al-Suyuti (may Allah have mercy on him) in his book Al-Khasa’is al-Kubra, in the chapter regarding the miracle in the Prophet’s excreta (Allah bless him and give him peace)… Hakim al-Tirmidhi narrates from ‘Abd al-Rahman ibn Qays al-Za’farani from ‘Abd al-Malik ibn ‘Abd Allah ibn al-Walid from Zukran that no shadow could be seen for the Prophet (Allah bless him and give him peace) in sunlight nor [could it be seen] in moonlight and his excreta did not leave behind any effect or remains. Imam al-Suyuti then comments: “Ibn Saba’ says ‘From his specialties (khasa’is) [and distinguishing characteristics] is that his shadow would not fall upon the earth and that he (Allah bless him and give him peace) was light (nur). When he would walk in sunlight or moonlight, no shadow would be visible.'” (Khasa’is; 1/71)
