What Rasoolullah Would Eat with Bread
Ash-Shama'il Al-Muhammadiyah 159
Anas ibn Malik said:
“The Prophet (Allah bless him and give him peace) used to admire the gourd, so when he was brought a meal or invited to one, I would seek it out and set it in front of him, because I knew that he liked it.”
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ‏:‏ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، وَعَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، قَالا‏:‏ حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم يُعْجِبُهُ الدُّبَّاءُ فَأُتِيَ بِطَعَامٍ، أَوْ دُعِيَ لَهُ فَجَعَلْتُ أَتَتَبَّعُهُ، فَأَضَعُهُ بَيْنَ يَدَيْهِ لِمَا أَعْلَمُ أَنَّهُ يُحِبُّهُ‏.‏

Explanation
comments
We gather from this that if there are many things in a plate, then it is permissible to take a thing which one likes from the other side of the plate, provided the next person does not feel offended. The reason for searching for pieces of gourd is because it was the custom to have more gravy in the curry. Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam also advised us to have more gravy in the curry so that the neighbours may also benefit.
