´It was narrated from 'Ubaidullah bin 'Abdullah bin 'Umar that his father said:` "The Messenger of Allah (ﷺ) was asked about water and how some animals and carnivorous beasts might drink from it. He said: 'If the water is more than two Qullahs, it will not become filthy.'"

´'Ubaidullah bin 'Abdullah bin Umar narrated that:` His father said: "The Messenger of Allah (ﷺ) prayed two rak'ahs in Mina, and Abu Bakr prayed two rak'ahs, and Umar prayed two rak'ahs, and Uthman prayed (two rak'ahs) at the beginning of his Khilafah."

´'Ubaidullah bin 'Abdullah bin 'Umar narrated that his father said:` "The Messenger of Allah stayed overnight in dhul-Hulaifah, where he started his Hajj with this action, and he prayed in the Masjid there.''(sahih)

´It was narrated from 'Ubaidullah bin 'Abdullah bin 'Umar that his father said:` "The Talbiyah of the Messenger of Allah was: "Labbaika Allahumma Labbaik, Labbaika la sharika laka labbaik. Innal-hamda wan-ni'mata laka wal-mulk, la sharika lak (Here I am, O Allah, here I am. Here I am, You have no partner, here I am. Verily all praise and blessings are Yours, and all sovereignty, You have no partner)." And Ibn 'Umar added: "Labbaika Labbaika wasa'daika wal-khayr fi yadika, warraghba' ilaika wal-'aml (Here I am, here I am, and at Your service; all good is in Your hands, seeking Your pleasure and striving for Your sake)."

´It was narrated from Ibn Shihab that Ubaidullah bin Abdullah told him that his father said:` "The Messenger of Allah joined Maghrib and Isha with no (Voluntary) prayer in between them. He prayed Maghrib with three Rakahs and Isha with two." And Abdullah bin Umar used to join them in like manner until he met Allahm, The Mighty and Sublime.
