Mishkat al-Masabih 4256
Asma' daughter of Yazid said:
The Prophet was brought some food which he offered to us, and when we said we did not want it he replied, "Do not combine falsehood with hunger." 

Ibn Majah transmitted it.
وَعَن أَسمَاء بنتِ يزِيد قَالَتْ: أُتِيَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِطَعَامٍ فَعَرَضَ عَلَيْنَا فَقُلْنَا: لَا نَشْتَهِيهِ. قَالَ: «لَا تَجْتَمِعْنَ جُوعًا وَكَذِبًا» . رَوَاهُ ابْنُ مَاجَهْ
