I said, "O Allah's Messenger (ﷺ)! Which mosque was built first?" He replied, "Al-Masjid-ul-Haram." I asked, "Which (was built) next?" He replied, "Al-Masjid-ul-Aqs-a (i.e. Jerusalem)." I asked, "What was the period in between them?" He replied, "Forty (years)." He then added, "Wherever the time for the prayer comes upon you, perform the prayer, for all the earth is a place of worshipping for you."
Sahih al-Bukhari Book 60, Hadith 97
← Previous Hadith The Prophet (ﷺ) said, "Solomon (the son of) David said, 'Tonight I will sleep with seventy ladies each of whom will conceive a child who will be a knight fighting for "Allah's Cause.' His companion said, 'If Allah will.' But Solomon did not say so; therefore none of those women got pregnant except one who gave birth to a half child." The Prophet (ﷺ) further said, "If the Prophet (ﷺ) Solomon had said it (i.e. 'If Allah will') he would have begotten children who would have fought in Allah's Cause." Shuaib and Ibn Abi Az-Zinad said, "Ninety (women) is more correct (than seventy).

Sahih al-Bukhari Book 60, Hadith 96 Next Hadith → Allah's Messenger (ﷺ) said, "My example and the example o the people is like that of a person who lit a fire and let the moths, butterflies and these insects fall in it." He also said, "There were two women, each of whom had a child with her. A wolf came and took away the child of one of them, whereupon the other said, 'It has taken your child.' The first said, 'But it has taken your child.' So they both carried the case before David who judged that the living child be given to the elder lady. So both of them went to Solomon bin David and informed him (of the case). He said, 'Bring me a knife so as to cut the child into two pieces and distribute it between them.' The younger lady said, 'May Allah be merciful to you! Don't do that, for it is her (i.e. the other lady's) child.' So he gave the child to the younger lady."
