Hadith 2672ـ وَبِهَذَا الإسْنَادِ قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) مَا فَتَحَ الله عَلَى عَبْدٍ بَابَ شُكْرٍ فَخَزَنَ عَنْهُ بَابَ الزِّيَادَةِ.
2. It is narrated through the same chain of narrators: “The Messenger of Allah has said, ‘Whenever Allah opens the door of gratitude to someone He does not keep the door of increasing (bounties) hidden from him.’”
