[Machine] The Prophet ﷺ used to meet a man and ask him, "O so-and-so, how are you?" The man would reply, "I am well, praise be to Allah." The Prophet ﷺ would then say to him, "May Allah keep you well." One day, the Prophet ﷺ met the man and asked him, "How are you, O so-and-so?" The man replied, "I am well, if I am grateful." The Prophet ﷺ remained silent, so the man said, "O Prophet of Allah, you used to ask me and say, 'May Allah keep you well,' but today you have remained silent." The Prophet ﷺ said to him, "I used to ask you and say, 'May Allah keep you well,' but today you said, 'I am well, if I am grateful,' so I remained silent."
أَنَّ النَّبِيَّ ﷺ كَانَ يَلْقَى رَجُلًا فَيَقُولُ يَا فُلَانُ كَيْفَ أَنْتَ؟ فَيَقُولُ بِخَيْرٍ أَحْمَدُ اللهَ فَيَقُولُ لَهُ النَّبِيُّ ﷺ جَعَلَكَ اللهُ بِخَيْرٍ فَلَقِيَهُ النَّبِيُّ ﷺ ذَاتَ يَوْمٍ فَقَالَ كَيْفَ أَنْتَ يَا فُلَانُ؟ فَقَالَ بِخَيْرٍ إِنْ شَكَرْتُ قَالَ فَسَكَتَ عَنْهُ فَقَالَ يَا نَبِيَّ اللهِ إِنَّكَ كُنْتَ تَسْأَلُنِي فَتَقُولُ جَعَلَكَ اللهُ بِخَيْرٍ وَإِنَّكَ الْيَوْمَ سَكَتَّ عَنِّي فَقَالَ لَهُ إِنِّي كُنْتُ أَسْأَلُكَ فَتَقُولُ بِخَيْرٍ أَحْمَدُ اللهَ فَأَقُولُ جَعَلَكَ اللهُ بِخَيْرٍ وَإِنَّكَ الْيَوْمَ قُلْتَ بِخَيْرٍ إِنْ شَكَرْتُ فَشَكَكْتَ فَسَكَتُّعَنْكَ
