Hadith.2044 - It is narrated from Yasir Al-Khadim, who said:
"I asked Al-Ridha عليه السلام: 'Can the Month of Ramadan ever be 29 days?'
Imam عليه السلام replied: 'The Month of Ramadan is never less than 30 days.'"
The compiler of this book (may Allah سبحانه وتعالى be pleased with him) comments:
"Whoever opposes these narrations and adheres to those that align with the views of the general public in contradiction to them should be treated with caution, just as the general public is treated cautiously. Such individuals should only be addressed with precautionary dissimulation (taqiyyah), whoever they may be, unless they are sincerely seeking guidance, in which case they should be guided and the truth clarified to them. For innovation is only eradicated and invalidated by refraining from mentioning it. There is no power except with Allah سبحانه وتعالى."
