The compiler of this book—may Allah سبحانه وتعالى have mercy on him—said: "This applies to both obligatory and recommended fasts." My father - may Allah سبحانه وتعالى be pleased with him, said in his message to me: "If you intend to travel and wish to fulfill some of the recommended fasts in advance, then fast three days for the month in which you plan to depart."
