On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) said:
"Allah said:
'Sons of Adam inveigh against [the vicissitudes of] Time, and I am Time, in My hand is the night and the day.'" (1)
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:
" قَالَ اللَّهُ: يَسُبُّ بَنِي بَنُو آدَمَ الدَّهْرَ، وَأَنَا الدَّهْرُ، بِيَدِي اللَّيْلُ وَالنَّهَارُ"
رواه البخاري (وكذلك مسلم)
