Sayyiduna Usayd (radi Allahu ta’ala ‘anhu) narrates:

The beloved Prophet of Allah (Salla Llahu ‘alayhi wa sallam) placed his sacred hands on the companion’s chest and rubbed them over his face. After that, whenever the companion (radi Allahu ta’ala ‘anhu) would enter a dark house it would lighten up.

[Imam Nabhani, Hujjatullah ‘Ala al-‘Aalameen, Page 438]
