English Translation of Al-Quran
[29].Surah Al-Ankabut [The Spider]
Ayat 65. And when they embark on a ship, they invoke Allah, making their Faith pure for Him only, but when He brings them safely to land, behold, they give a share of their worship to others.
Ayat 66. So that they become ingrate for that which We have given them, and that they take their enjoyment (as a warning and a threat), but they will come to know.
Tafseer of Surah Al-Ankabut (The Spider) Ayat 65. Now, if they embark on a boat, they call on Allah, making their devotion sincerely (and exclusively) to Him; but when He has delivered them safely to (dry) land, behold, they give a share (of their worship to others)!- Cf. 7:29 , where I have slightly varied the English phrase according to the context. It was shown in the last verse that the life of this world is fleeting, and that the true life—that which matters—is the Life in the Hereafter. In contrast with this inner reality is now shown the shortsighted folly of man. When he faces the physical dangers of the sea, which are but an incident in the phenomenal world, he actually and sincerely seeks the help of Allah; but when he is safely back on land, he forgets the Realities. Plunges into the pleasures and vanities of fleeting phenomena, and his devotion, which should be given exclusively to Allah, is shared by idols and vanities of his own imagination. 66. Disdaining ungratefully Our gifts, and giving themselves up to (worldly) enjoyment! But soon will they know. Such folly results in the virtual rejection (even though it may not be express) of Allah and His Grace. It plunges man into the pleasures and vanities that merely delude and are bound to pass away. This delusion, however, will come to an end when the true Reality of the Hereafter will shine forth in its entire splendor.
English Translation of Hadith
Hazrat Umar bin Al-Khattab (May Allah be pleased with him) said: The Messenger of Allah 
[SAWW](PBUH), “The deceased is tortured in his grave for bewailing over him.”
[Al-Bukhari Book 02, Chapter 23, Hadith # 379]
Lesson: “Bewailing” is wailing over the dead. It is weeping loudly for the deceased describing his noble qualities or the problems created by his death. Wailing causes trouble to the deceased if he willed his heirs to do so, or in his own life he behaved in the same manner and his family members were following his style of mourning at his death. But if the deceased had forbidden his relatives from wailing over his death and they, do it despite his warning against doing so, then the deceased will not suffer any torment on their wailing because his intention and training have no connection with it. The Quranic injunction in this matter is absolutely clear: “No one laden with burdens can bear another’s burden.” (17:15).
