Abdullah bin Umar reported,

He was sitting in his gathering in the mosque, and when the time for prayer came, he stood up, performed ablution, prayed, then returned to his gathering. When the time for the afternoon prayer came, he stood up, performed ablution, prayed, then returned to his gathering. When the time for the sunset prayer came, he stood up, performed ablution, prayed, then returned to his gathering.I asked, "May Allah set you right, is performing ablution before every prayer obligatory or a recommended practice?"He replied, "Did you notice this about me?"I said, "Yes."He said, "No. If I had performed ablution for the dawn prayer, I could have prayed all the prayers with it as long as I did not break my ablution. But I heard the Messenger of Allah ﷺ say, 'Whoever performs ablution upon already being in a state of purity will receive ten good deeds.' I simply desired those good deeds."

حدثنا محمد بن يحيى حدثنا عبد الله بن يزيد المقرئ حدثنا عبد الرحمن بن زياد عن أبي غطيف الهذلي قال

سمعت عبد الله بن عمر بن الخطاب

في مجلسه في المسجد فلما حضرت الصلاة قام فتوضأ وصلى ثم عاد إلى مجلسه فلما حضرت العصر قام فتوضأ وصلى ثم عاد إلى مجلسه فلما حضرت المغرب قام فتوضأ وصلى ثم عاد إلى مجلسه فقلت أصلحك الله أفريضة أم سنة الوضوء عند كل صلاة قال أو فطنت إلي وإلى هذا مني فقلت نعم فقال لا لو توضأت لصلاة الصبح لصليت به الصلوات كلها ما لم أحدث ولكني سمعت رسول الله ﷺ يقول من توضأ على كل طهر فله عشر حسنات وإنما رغبت في الحسنات
