Sunan Abi Dawud, 2320

Rapporté par Ibn ‘Umar رضي الله عنه : « Le Messager d’Allah ﷺ a dit : “Le mois compte vingt-neuf jours, mais ne commencez pas le jeûne tant que vous ne l’avez pas vu (le croissant de lune), et ne rompez pas le jeûne tant que vous ne l’avez pas vu. Si le ciel est couvert, comptez trente jours.” Quand arrivait le vingt-neuvième jour de Sha’ban, Ibn ‘Umar envoyait quelqu’un observer la lune pour lui. Si on la voyait, tant mieux ; sinon, et s’il n’y avait ni nuages ni poussière à l’horizon, il ne jeûnait pas le lendemain. S’il y avait des nuages ou de la poussière, il jeûnait le lendemain. Ibn ‘Umar rompait le jeûne avec les gens, et ne suivait pas ce calcul. »

Ibn ‘Umar reported the Apostle of Allaah(ﷺ) as saying “The month consists of twenty nine days, but do not fast till you sight it (the moon) and do not break your fast till you sight it. If the weather is cloudy, calculate it thirty days. When the twenty-ninth of Sha’ban came, Ibn ‘Umar would send someone (who tried) to sight the moon for him. If it was sighted then well and good, in case it was not sighted and there was no cloud and dust before him (on the horizon) he would not keep fast the next day. If there appeared (on the horizon) before him cloud or dust, he would fast the following day. Ibn ‘Umar would end his fasting alone with the people and did not follow this calculation.”
