وَمِنْ ءَايَٰتِهِۦ يُرِيكُمُ ٱلْبَرْقَ خَوْفًۭا وَطَمَعًۭا وَيُنَزِّلُ مِنَ ٱلسَّمَآءِ مَآءًۭ فَيُحْىِۦ بِهِ ٱلْأَرْضَ بَعْدَ مَوْتِهَآ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَعْقِلُونَ
And of His signs is this: He showeth you the lightning for a fear and for a hope, and sendeth down water from the sky, and thereby quickeneth the earth after her death. Lo! herein indeed are portents for folk who understand.
Surah Ar-Room(30:24)
Sahih al-Bukhari
Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The signs of Prophethood in Islam
Narrated Anas bin Malik:
That he heard Jabir bin `Abdullah saying, "The roof of the Mosque was built over trunks of datepalms working as pillars. When the Prophet (ﷺ) delivered a sermon, he used to stand by one of those trunks till the pulpit was made for him, and he used it instead. Then we heard the trunk sending a sound like of a pregnant she-camel till the Prophet (ﷺ) came to it, and put his hand over it, then it became quiet."
