عَنْ عَبْدِ اللَّهِ بْنِ السَّائِبِ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُصَلِّي قَبْلَ الظُّهْرِ بَعْدَ الزَّوَالِ أَرْبَعًا وَيَقُولُ: ((إِنَّ أَبْوَابَ السَّمَاءِ تُفْتَحُ فَأُحِبُّ أَنْ أُقَدِّمَ فِيهَا عَمَلًا صَالِحًا))
Sayyiduna Abdullah bin Sa’ib (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him and his family) used to perform four rak‘ahs before Zuhr but after the sun had passed its zenith, and he used to say: At this time, the gates of the heavens are opened, and I like that a righteous deed of mine be raised up in it.
