أَنَّهُ كَانَ يَقُولُ «لَا يَصُومُ إِلَّا مَنْ أَجْمَعَ الصِّيَامَ قَبْلَ الْفَجْرِ»
"Whoever does not intend to fast before dawn comes, should not fast." (Daif)

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "Only some one who makes the intention to fast before dawn (actually) fasts."
