Narrated 'A’isha said (may Allah be well pleased with her):
“The foreleg was not the meat dearest to Allah’s Messenger (Allah bless him and give him peace), but he only got to have meat occasionally, so he would rush to it, because it was the part that got done the most quickly.”
"I cooked a dish for the Prophet (Allah bless him and give him peace), and he used to take great pleasure in the foreleg ,so I passed him the foreleg. Then he said: 'Pass me the foreleg,' so I passed it to him. Then he said: 'Pass me the foreleg,' so I said: 'O Messenger of Allah, how many forelegs does a sheep have?' He said: 'By the One in whose Hand is my soul, if you kept silent, you would surely pass me the foreleg whenever I asked for it!’”
