It was narrated from 'Abdullah bin Mas’ood that

Subai'ah bint al-Harith gave birth fifteen days after her husband died. Abus-Sanabil entered upon her and said: It is as if you are thinking of getting married, You cannot do that until you complete the longer of the two periods. She went to the Messenger of Allah (ﷺ) and told him what Abus-Sanabil had said. The Messenger of Allah (ﷺ) said: Abus-Sanabil is lying. If someone comes to you who is pleasing to you, then bring him to me - or he said: Tell me, And he told her that her iddah had ended.
