Do not make love with your wife on the eve of mid-Sha’baan...
Do not make love with your wife on the eve of mid-Sha’baan, for if a child were conceived as a result, the child would be disfigured with large spots on his face. Do not make love with your wife if there were two days left to the (lunar) month, for if a child were conceived as a result, s/he would be cAshshaar (inspector/collector of tax (which is illegal from the Islamic point of view)), or an assistant to the oppressor, and many people would perish at their hands.
Do not make love with your wife on the roof top of a building, for if a child were conceived as a result, s/he would be hypocrite, show-off, and commit Bid’ah. If you have travelled, do not make love with your wife on that night, for if a child were conceived as a result, s/he would give his/her money in a false way, [then Rasulollah (S) recited] ..Verily the spendthrifts are the brothers of the Satans...
