Why he sent back a gift after one prayer
He had prayed in it once and that was enough.
اذْهَبُوا بِخَمِيصَتِي هَذِهِ إِلَى أَبِي جَهْمٍ وَائْتُونِي بِأَنْبِجَانِيَّةِ أَبِي جَهْمٍ، فَإِنَّهَا أَلْهَتْنِي آنِفًا عَنْ صَلاَتِي
Idhhabū bi-khamīṣatī hādhihi ilā Abī Jahm, wa-ʾtūnī bi-anbijāniyyati Abī Jahm, fa-innahā alhatnī ānifan ʿan ṣalātī
Take this patterned cloak of mine to Abu Jahm and bring me Abu Jahm's plain one, for it just now distracted me from my prayer.
Where this comes from
Abu Jahm had given him a cloak with markings on it. He prayed in it, looked at the patterns, and afterwards sent it straight back and asked for the coarse plain one instead.
The full narration
Narrated `Aisha:the Prophet (ﷺ) prayed in a Khamisa (a square garment) having marks. During the prayer, he looked at its marks. So when he finished the prayer he said, "Take this Khamisa of mine to Abu Jahm and get me his Inbijaniya (a woolen garment without marks) as it (the Khamisa) has diverted my attention from the prayer." Narrated `Aisha: The Prophet (ﷺ) said, 'I was looking at its (Khamisa's) marks during the prayers and I was afraid that it may put me in trial (by taking away my attention)
