Mishkat al-Masabih, hadith 2368

وَعَنْ عَائِشَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَظَرَ إِلَى الْقَمَرِ فَقَالَ: «يَا عَائِشَةُ اسْتَعِيذِي بِاللَّهِ مِنْ شَرِّ هَذَا فَإِنَّ هَذَا هُوَ الْغَاسِقُ إِذا وَقب» . رَوَاهُ التِّرْمِذِيّ

‘A’isha told of the Prophet looking at the moon and saying, “Seek refuge in God from the evil of this one, ‘A'isha, for this is the darkness when it overspreads.” 2 2. cf. Qur’an, cxiii, 3. The tradition is said to refer to the moon being eclipsed. Tirmidhi transmitted it.
