Sunan Ibn Majah, 945

It was narrated from Busr bin Sa’eed that Zaid bin Khalid sent word to Abu Juhaim Al-Ansari asking him:“What did you hear from the Prophet (ﷺ) about a man when he is performing prayer?” He said: “I heard the Prophet (ﷺ) saying: ‘If anyone of you knew (how great is the sin involved) when he passed in front of his brother who is performing prayer, then waiting for forty’,” (one of the narrators) said: “I do not know if he meant forty years, forty months, or forty days, ‘would be better for him than that.”

Rapporté par Busr bin Sa’eed : Zaid bin Khalid a envoyé demander à Abu Juhaim Al-Ansari : “Qu’as-tu entendu du Prophète (ﷺ) à propos d’un homme qui prie ?” Il a répondu : “J’ai entendu le Prophète (ﷺ) dire : ‘Si l’un de vous savait (la gravité du péché) de passer devant son frère qui prie, alors attendre quarante’,” (un des rapporteurs) a dit : “Je ne sais pas s’il voulait dire quarante ans, quarante mois ou quarante jours, ‘serait mieux pour lui que de passer devant.’”
