Ibrahm Malik (or Ibrahim Malik Bayyu, Ibrahim Malick) (born near Kamta, in Afghanistan) is the progenitor of the Malik Muslim community of Bihar, India.

His ancestors had migrated to the region from Baghdad to escape from persecution at the hands of the Abbasids. Ibrahim Malick came to India in 740 Hijri (1339 AD), where he served as a general in Sultan Mohammad Tughlaq's army. After several successful battles and campaigns he received the title of Mallick Biya from the Sultan Tughlaq, and was later appointed the Governor of the district of Bihar by the Sultan's son.^{[citation needed]}

Ibrahim Malick settled in Bihar Shareef (India) with his family, and ruled over the region until his assassination on Monday, 13th Zul-Hijjah, 753 Hijri (1353 AD).

Ibrahim I (Ottoman Turkish: ابراهيم اول) (November 5, 1615 – August 18, 1648) was the Sultan of the Ottoman Empire from 1640 until 1648. He was born in Constantinople the son of Ahmed I by Valide Sultan Kadinefendi Kösem Sultan, an ethnic Greek originally named Anastasia. He was unofficially called Ibrahim the Arrage (Turkish: Deli İbrahim) due to his mental condition.

One of the most famous Ottoman Sultans, he was released from the Kafes and succeeded his brother Murad IV (1623–40) in 1640, though against the wishes of Murad IV, who had ordered him killed upon his own death. Murad IV had himself succeeded their older brother Osman II in 1622, and had ordered his three other brothers executed. Ibrahim I was allowed to live because he was too mad to be a threat. Ibrahim brought the empire almost to collapse in a very short space of time — paralleled only perhaps to the rule of Phocas (602–610) in the Byzantine Empire. Probably mentally unstable, he is claimed to have suffered from neurasthenia, and was also depressed after the death of his brother. His reign was essentially that of his mother, Mâh-Peyker Kösem Valide Sultan, who was no longer hindered in controlling the empire as she willed.
