Sheikh `Abdul-Majeed Subh, a prominent Azharite scholar, states: “When the husband intends to travel, he should say goodbye to his wife. However, it is appropriate to take the following points into consideration:
1- The period, which the husband intends to stay away from his wife, should not exceed four-month.
2- It is better for the two spouses, on the night prior to the departure day, to exchange mutual love affection for that might leave a sweet experience upon traveling.
3- Both the husband and wife should utter what is known as the farewell supplication (Du`a’ al-Wada`). In the farewell supplication, the departing person or the husband should say, ‘Astawdi`ukum Allah alladhi la tadee`u wada’`huh (I am departing while leaving you as a trust safeguarded by Allah Whose trusts are safe and secure).’ In return, the wife should say: ‘Astawdi`u A
llaha deenaka wa’amanataka wa khawateema `amalek. Zawwadaka Allahu bitt-taqwa. Waghafara laka zanbak. Wayassara laka al-khayr haythukan (You religion, honesty and the last righteous deeds you have done are a trust safeguarded by Allah. May Allah increase your piety, forgive your sins, and facilitate all what is good and righteous anywhere you go).’
4- During the period of his traveling, the husband should rest assured that his wife will be in a safe abode and cared for by one of her mahram (a person who a woman is not permitted to marry) relatives.
5- When it is time to leave, the wife should advise her husband to seek lawful means in earning his livelihood, fear Allah in all of his dealings. In early Islamic eras, the righteous woman would address her husband upon leaving the house saying: ‘Fear Allah regarding us; we may withstand hunger but we cannot withstand the Hell-fire.'”
