Hadith Qudsi:On the authority of Abu Hurayrah , who said that the Messenger of Allah (peace be upon him) said: Allah said: Sons of Adam inveigh against Time, and I am Time, in My hand is the night and the day .As the Almighty is the Ordainer of all things, to inveigh against misfortunes that are part of Time is tantamount to inveighing against Him.
Hadith Nabwi:On the authority of Ibn Omar, the son of Omar bin Al-Khattab,, who said : I heared the messenger of Allah say : “Islam has been built on five [pillars]: testifying that there is no god but Allah and that Muhammed is the messenger of Allah, performing the prayers, paying the zakat, making the pilgrimage to the House, and fasting in Ramadan."
