Abdullah bin Abi Labid عبد الله بن أبي لبيد · The Book of Fasting

"The messenger of Allah said: 'Do not fast one or two days ahead of the month, unless that happens to be a day that one of you habitually fasts."' Abu 'Abdur-Rahman (An-Nasai) said: This is a mistake. '

"The Messenger of Allah would not break fast on the days of Al-Bid whether he was a resident or traveling."
