It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) was on a military expedition or a journey and night came upon him, he would say: 'Ya ardu, rabbi wa rabbuki Allah, a'udhu billahi min sharri kulli asadin, wa sharri kulli aswada, wa hayyatin wa 'aqrabin, wa min sakini al-baladi, wa min sharri walidin wa ma walad' (O earth, my Lord and your Lord is Allah. I seek refuge in Allah from the evil of every beast of prey, from the evil of every black snake, from snakes and scorpions, from the evil of the inhabitants of this place (the jinn), and from the evil of the father (Iblis) and his offspring). This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.
