2189 سمع الله لمن حمده، اللهم ربنا لك الحمد، ملء السماوات وملء الأرض وملء ما شئت من شيء بعد
Allah hears he who praises Him. O Allah, our Lord, to You is the praise as much as fills the heavens, as much as fills the earth, and as much as fills whatever You will after that

عن ابن أبي أوفى قال: كان رسول الله صلى الله عليه وسلم إذا رفع ظهره من الركوع قال: «سمع الله لمن حمده، اللهم ربنا لك الحمد، ملء السماوات وملء الأرض وملء ما شئت من شيء بعد».

Ibn Abi Awfa (may Allah be pleased with him) reported: When the Messenger of Allah (may Allah’s peace and blessings be upon him) raised his back from rukū‘, he would say: "Sami‘a allahu liman hamidah, allahumma rabbana laka al-hamd mil’ as-samawati wa mil’ al-ardi wa mil’ ma shi’ta min shay’in ba‘d" (Allah hears he who praises Him. O Allah, our Lord, to You is the praise as much as fills the heavens, as much as fills the earth, and as much as fills whatever You will thereafter).

صحيح - ( رواه مسلم ). Sahih/Authentic. [Muslim]

كان النبي صلى الله عليه وسلم إذا رفع ظهرَه مِن الركوع في الصلاة يقول: سمع الله لِمَن حمده، ومعنى سمع هنا: أجاب، ومعناه: أنّ مَن حمد الله تعالى استجاب الله تعالى له، وقَبِل حمدَه وأثابه، فهذا الحمد مِلْء السَّماوات ومِلْء الأرض ومِلْء ما شِئْت، أي: الذي شِئْتَه مِن شيءٍ بَعْدُ، أي: العرش والكرسي ونحوهما ممّا في مقدور الله عزَّ وجلّ، فهذا الذِّكْر يُستَحَبّ قوله عند الرَّفع مِن الركوع، والتَّسميعُ مشروعٌ في حقّ الإمام والمأموم والمنفَرِد، والتَّحميد مشروعٌ في حقّ الجميع.
Whenever the Prophet (may Allah’s peace and blessings be upon him) raised his back from rukū‘ in prayer, he would say: Allah hears he who praises Him. 'Hear' here means: respond. So, it means that when a person praises Allah Almighty, He responds to him and accepts the praise from him and rewards him for it. The praise is as much as fills the heavens, as much as fills the earth, and as much as fills whatever You will after that - i.e., the Throne and the Kursī and other things, which are within Allah's power. It is recommended to say this dhikr upon rising from rukū‘. It is legitimate for everyone - the Imām, those led in prayer, or those praying alone - to say "Allah hears he who praises Him" and the response to it.

بيان ما يستحب أن يقوله المصلي إذا رفع رأسه من الركوع. بيان مشروعية الاعتدال ووجوب الطمأنينة فيه؛ لأنه لا يمكن أن يقول هذا الذكر إلا إذا اعتدل واطمأن. هذا الذكر مشروع في جميع الصلوات سواء كانت فرضًا أو نفلًا.
The Hadīth demonstrates what a praying person is recommended to say upon raising his head from rukū‘. It points out the Sunnah of straightening one's back and the obligation of doing so with tranquility, for a person cannot say this dhikr unless he keeps
