Hadith 31-14

وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ‏ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: النُّجُومُ أَمَّانٌ لاهْلِ السَّماءِ وَأَهْلُ بَيْتِي أمانٌ لاُمَّتي.

According to the same documentation, God’s Prophet (S) said, “The stars are the safeguards for the residents of the heavens, and the members of my Household are the safeguards for my nation.”
